HazelNuts39:
The text on page 6 is not entirely clear to me. Does it mean that stall warning in Alternate Law 1 occurs at an AoA corresponding to ‘between 5 and 10 kt’ above stall speed?
Yes, that's what it means.
The last sentence (Pour terminer ...) is not understood. If it means that stall warning is lost, that would contradict the procedure which aims to retain stall warning by keeping one ADR ‘online’.
My tentative translation:
"Finally, it is worth noticing that PITOT and TAT probes icing entails first the << F/CTL ADR DISAGREE>> message pop up, which then generates switching to <<ALTERNATE LAW 2>> and, in this case, loss of <<LOW SPEED STABILITY>> protection."
the <<LOW SPEED STABILITY>> protection is described in the first part of the paragraph. Since the system can no longer determine if there remains a valid airspeed, it seems logical to cancel the protection. That does not preclude stall warnings based on AoA.
btw, I doubt that TAT probe icing plays a role in this sequence.
