All very interesting. As you know the SS commands G. So the a/c was in unusual attitude law during it's decent. So manual fwd trim would be required to position the stab in the required direction. OK
I would like to see what position the elevators would have maintained had the flying pilot held full fwd SS. I hope full down, but would they? The reason for my interest is that the aircraft was in a very unusual position and attitude which I wonder how much testing was done by airbus in that part of the envelope.
(Recent Sim exercise we could not get the a/c into the unusual attitude law & speed only got down to 120Kts with VS -6000'/min. fwd stick was not really enough to get the nose down but as the stab would run with the SS held fwd the aircraft recovered fine. But trouble is the sim is unreliable outside the normal flt envelope)

As to any pilot thinking + 16 NU at 30+ thousand feet must have dismissed the attitude indicators as well as the airspeeds as it looks really weird.
