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?
