He is not correct and with the bracha of Al Achilat matzah you di fulfil your basic obligation of saying a bracha. If you said Baruch Atta Hashem …Melech HaOlam and you mention the thing you are eating you made a bracha.
Explanation:
Gemara in Brachot 40a: One who sees bread and says, “How nice is this bread, blessed is Hamakom who created it, “ he can eat it (it is considered a bracha). If he sees a fig and says, “How nice is this fig, blessed is Hamakom which created it, it is fine, so said R’ Meir. R’ Yossi said anyone who changes the wording which the Rabbis established did not fulfil his obligation of bracha.
The Kesef Mishna (Brachot1:9) writes that eh R’ Meir and R’ Yossi argue in one of two cases 1) if someone changes the wording of a bracha whether he fulfills obligation of saying a bracha before eating. Like if he says, “Blessed is he who created,” which is a very general bracha and does not mention the type of food, R’ Meir says he is fine and R’ Yossi argues.
2) the argue about the fact that he din to say the Name of Hashem and mention His Malchut, R’ Meir says he is fine and R’Yossi says he isn’t, but everyone agrees if he said Baruch Atta Hashem… Melech HaOlam and just adds in SheBarah(that he created) on his own it is fine.
The Kesef Mishna understood like the second possibility.
The Rambam (Kriat Shema 1:7) writes: Where the chachamim instituted a bracha with concluding bracha (like Asher Yatzar) one may not omit it, and where they didn’t, he may not add a conclusion. Where they instituted not to open with Baruch, he may not open with Baruch, and where they did, he may not omit it. The rule is anyone who changes the words which the Chachamim instituted errs and he must say anew bracha.
The Rambam in Brachot (1:5)writes: the phrasing of the Brachot was instituted by Ezra and his Beit din and one is not allowed to change them, nor add to them nor subtract and anyone who changes the words is in error.
The Ramach there asks why in Hilchot Kriat Shema does the Rambam add that the must say the bracha over again but in Brachot he just says he made an error?
The Kesef Mishna answers the Rambam in Kriat Shema is discussing a person who add end in a Baruch Atta in Bichat Kriat Shema where he was not supposed to or didn’t say a Baruch where he was supposed to therefore, he says he must repeat birchot Kriat Shema. However, in Hilchot Brachot he is talking about someone who changes the bracha a little but doesn’t change the beginning or end.
The Kesef Mishna adds that Rambam rules like R’ Yossi that if he concludes or doesn’t conclude where the chachamim told him, did nothing.
The Gra answers the Rambam differently (OH 68:1): The Rambam in Hilchot Brachot is retracting what he said in Kriat Shema and he rules like R’ Meir that even if he changes the wording completely, he fulfills his obligation.
The Gemara in Brachot 40b: Binyamin the shepherd took read and said , “Blessed is the master of this bread.” Rav said he fulfilled his obligation. But Rav said nay bracha where he does not mention the name of Hashem is not a bracha? No, he said, Blessed is Rachmana, the master of this bread. Gufa- Rav said any bracha which he does not say the name of Hashem is not a bracha and R’ Yochanan said any bracha without Malchut (Melech Haolam) is not a bracha.
The Shulchan Aruch (Oh 167:10) writes: If instead of Hamotzi he said Shehakol or even if he said “Brich Rachmana Malka Mora D’Hai Pita, “ He fulfills his obligation.
The Mishna Berura adds if he just says Mora D’hai but leaves out bread (Pita) it could be he fulfills his obligation since the brad is in front of him.
The Shulchan Aruch (214) writes: Any bracha which is missing the name of Hashem or Melech is not a bracha and if he skips it eh must go back and make a new bracha. Even if he just skips Haolam he must go back since Melech alone is not sufficient and he needs to say Melech Haolam.
The integral words a of a bracha are
Baruch-he must say (Mishna Berura 213:19)
Attah-not required Bdiavad. (Mishna Berura 214:3)
Hashem- required (Shulchan Aruch 214)
Elokeinu-not required (Biur Halcha167)
Melech-required
Haolam- R’ Ovadia Yosef writes that if he forgot to say Haolam he does not have to go back since it is a safek Brachot. In Chazon Ovadiah he writes that if he forgot it, he must repeat the bracha but if he said Melech without Haolam he does not have to go back ( so writes the Biur Halacha 214)
Lechem or Pat- he must specify if it is not in front of him in which case, he may say Zeh.
So, al Achilat matzah was sufficient.
