For the avoidance of doubt - I have checked the relevant FCOM:
Alpha - floor (which incidentally is simply an A/THR mode independent of FBW protections) signal is provided by the FAC, when the AOA is above a predetermined threshold, which is a function of the configuration. It is available from lift-off until the a/c reaches 100 ft. RA in approach.
Alpha-floor is lost under alternate or direct flight control law. (one of eight loss-making conditions).
i.e Alpha-floor is only available in Normal Law
Regarding who is "drivers" and who ain't - unless a PPRuNer's profile states licence type and a/c - I assume they are not pilots. But I don't assume they don't know what they are writing about, unless it is obvious from what they write.
