Once they were deep into the incident the warning worked bass ackwards; they reduced AoA, speed increased beyond 60KIAS, the stall warning sounded, they pulled back again, speed reduced, and the stall warning stopped.
This is possibly far more significant than the reports suggest.

The stall warning was clearly misbehaving so they would have ignored it and concentrated on the unwinding altimeter and the overspeed warnings.
I didn't know they were getting over-speed alerts as well?? Are you sure?
