In my post #1143 (p.58) I wrote:
If alpha-prot had been activated prior to reversion to ALT law, and continued to be active after that point, it would maintain AoA at alpha-prot, i.e. it would not lead to deep stall. On the other hand, it may have handed the pilots an aircraft at relatively high AoA, low speed and possibly unusual pitch attitude.
That is correct if the indicated airspeed is correct. If the pitots freeze and IAS drops to a low value, it's quite another story. But that is too many if's, I suppose, just like Machinbird's famous 'pressure cooker', that still intrigues me.
