The stabiliser was nose up not down. That's why the full down elevator was not effective in reducing the pitch attitude - for more gen read my post back one page.
I would agree in principle. However, for sometime it did seem to be holding pitch, and then something seemed to change? See 15:45:18 say - pitch is actually reducing (slowly), speed ~130K, full fwd stick, quite a lot of roll (it's rolling from side to side), and full power is on... it seems "OK" until :21
