Assuming the PF was sane and coherent, (I do), NU would be input to counterract ND, or a descent of some sort. After his correction, neutral stick. If the slight rotation he commanded (NU) then appeared too much, he would input ND (he did). Wait, that did not work, she still climbs. A bit more ND, and what is that pesky Roll? More Roll? compensated. More Roll still? and continued Climb? Increasing climb rate?? More ND and More.
BEA tells the Truth, and I see it this way. By BEA's data alone, where is PF screwing anyone's pooch on the way up? On the way down, with gobs of AoA, the Pitch can reverse with a Stalled Tail Plane. Remember this is not so much a Tail as a variable incidence wing.
JD-EE. Chronic and slow enough to allow the TailPlane to trim for it. And engines to develop max thrust (or close to it).
