Hi,
Is this "Abnormal Law" dispatched for the PF?
Doesn't be curious BEA note doesn't not mention this?
One more question:

The stall warning sounded twice in a row. The recorded parameters show a sharp fall from about 275 kt to 60 kt in the speed displayed on the left primary flight display (PFD), then a few moments later in the speed displayed on the integrated standby instrument system (ISIS).
Why ISIS speed display goes down? Isn'it inertial? I don't understand how they can truly loose all that speed before ascending.
