As
Gums has implied, the Vertical Stabilizer coupled with the Rudder is the only airfoil capable of behaving with any degree of reliability at such an extreme AoA when dropping like a stone with limited IAS.
So when outside the known envelope, some g-estimates are inevitable, and further study of the DFDR gives evidence that some of the roll component is being driven by the Yaw Damper, i.e. the YD is leading the roll by between 1 and 2 seconds.
Clandestino;
Yes, your post is noted, and the input of those with experience in military types may actually be of value in understanding the aerodynamics
experienced by this unlucky A330.
