If you read the AirCaraibe report, there they mention exactly the discrepancy of respecting S/W or not to.
ECAM status page stating:
"RISK OF UNDUE STALL WARNING" and
"UNDUE STALL WARNING MAY MAINLY OCCUR IN CASE OF AN AOA
DISCREPANCY"
Could it be, that the AF447 PF thought of Air Caraibe crew ignoring the S/W? Still would not justify pitching up to >10° at FL350.
What if he simply mixed up values of memory items below and above FL100 as he did UAS in the simulator not long before the accident.
Anyway, PNF would have had to at least call out "PITCH" and they probably would have broken the chain of events. Were they both so stunned, that neither of them thought of calling for the QRH?
May be BEA report to come will give more insight.........
