You mean airspeed becomes part of the calculation even if the alternate law has been triggered by an ADR disagreement ?! (corrupted airspeeds)
This would justify the ECAM status message "risks of undue stall warning" (that should be discarded according to certain SOPs, because the stall alarms are supposed to be based on the AoA and not the airspeeds)
