I gather you have conceeded that the Beis Yosef, Rama and Shach do not rule that way, and it is not the accepted Halacha.
Yes, it does seem that he conceded this point.
it is clearly not the Rambam’s intent.
Although, to be fair, R’ Moshe seems to lean towards understanding the Ramba”m that way, although he emphatically states that the halacha is not that way.
