What are you guys exactly trying to determine? Apart from reenacting the event...
Simply what happens when you pull the stick fully aft and keep it there?
Could it be that airbus decided to write that valpha-max may be reached by pulling full aft sidestick, because of the habsheim accident?
To me the sidestick input certainly does not look like he wanted to reach valpha max throughout. According to the figure in page 7 he only reached max aft side stick in the last few seconds.
With loadfactors changing, engines spooling up, wind changing... the flight control computers might simply not have had enough time to reach valpha max (before crashing).
Therefore some lawyer decided to write may be reached.
