Sorry, but it seems you are the one confused here.
What is quoted, with illustration, is only the manual, word for word, until the last sentence. Each part quoted is detailing a protection in NORMAL Law and what happen when mode switch to ALTERNATE (generic, as per the manual). Only the last sentence of each paragraphe is an addition which is explicitly telling what was the "real" condition in ACA case.
Read it again, it ends with "dans ce cas ... cette protection est perdue" (this protection is lost) for each of them, except for the load factor protection (no low/high speed stability after the rejection of all ADRs by the PRIMs).
Consequently, it is all taken from the manual and there is no need for one to refer to any hypotetical confusing Airbus engineers "quote".
