i suspect it was an FCS issue. pitch inputs went through at the usual rate but roll rate for some reason was greatly reduced. pitch got mixed into the roll at the wrong time turning what should have been an aileron roll into a barrel roll
with roll maneuvers the plane falls in nose attitude because obviously you're losing lift at perpendicular and inverted roll angles so you always have to pitch to correct the flight path afterwards. if the pilot was operating on muscle memory to be commanding pitch after the roll, but the roll rate was quartered, then it would result in pitch up being commanded while the plane is still inverted. that's what looks to me as the best description of the maneuver immediately before the crash.
