Given the very high AoA during the descent, it is surprising that the ailerons were effective enough for roll to be (reasonably) controlled. Not much point looking at how well teh PF controlled roll under these circumstances, at least in terms of judging his sidestick touch. Presume the ailerons were acting as drag modulating devices rather than Cl adjusters. Not so very much more and the wing would have been going backwards (AoA >90 degrees).
Interesting quotes though, so thanks again.
