Building on the above. I think that what is important here is the rate of change of thrust vs time, vs the rate of change of pitch (due to thrust changes) vs rate of change of airspeed.
In the long and short of it, in spte of the guesses, a little DFDR data could go a long way towards establishing if the aircraft had already reached a critical AoA before the thrust was changed or the thrust change preceeded it.
Some of the posts while intelligent and well intentioned are leading too far ahead of any confirmed useful facts.
