BEA's 275 kCAS at FL350 equates to M=0.808. Yes, pitching up results in an increase of AoA and vertical acceleration, and FPA, for example AoA=4.5, FPA=5.5, Pitch =10 degrees at about 1.33 g.

Which one, please elaborate.
All of them: max 7000 fpm, min 700 fpm, 215 kt at FL375 at 2:10:50, maximum altitude FL350 at 2:11:06, just to name a few.
At 02:10:20 FL 375 was reached (according the graph from A33Zb, ...)
I don't know how that has been derived, I would put it closer to 2:10:53. I don't think the difference between CLB and TOGA at FL375 is that significant.
So most of the beyond 10° pitch in that timeframe produced only AOA and not much climb at all.
Between 2:10:15 and 2:10:35 pitch was reduced to about 5 degrees in order to reduce RoC from 7000 to 700 fpm.

I hope that explains the flight mechanics.
