But still, in post 1393 it says that the elevators are also fully stalled, so can they still have some nose down authority?
The elevators were max NU and held the attitude at +16°. I wouldn't get too excited about the stalled tailplane, as the drag caused by the vortex was assisting its lift, and airflow over the aerofoil, i.e. the THS and/or elevators, need only act as a lever to force the NU or ND as required.

Suggest you have a good look at some of the posts in the Tech Log to get an understanding of how the alpha protections and the associated autotrim work in Normal and Alternate Laws. Have a read of the Andy Tracy document at A340 - A330 Control: Flight & Laws, which is a summary of the basic flight laws for the A330 and A340.
