Again, if PF had not made himself aware of Law change, and was functionally still in Normal, these inputs would not do harm. (Roll left, full aft stick).
Dropping a/p does not command degradation out of Normal Law. Could he have been that far behind? It takes AD disagrees to autoselect ALTLAW. So at what point were they aware of AD disagree , and how long after that before they acclimated there 'get'/'got' to new parameters?
From the report:
"2 h 10 min 05 , the autopilot then auto-thrust disengaged and the PF said "I have the controls"."
"At 2 h 10 min 16, the PNF said "so, we’ve lost the speeds" then "alternate law […]"."
So the PF should have been aware of the change within seconds.
There is no indication in the report of any other input recognized by the PF, other than putting the nose down as the stall warning sounded the first times.
