No Dozywannabe. The PF acted on the elevators, not THS. If the PF acted on the THS, that would have been Manual THS Control.
It was an algorithm in the FBW system that decided to move the THS to max UP position, during the exact period of time in which the STALL WARNING was ON, in spite of the elementary rule, which now is recognized straight forward by Airbus that the STALL is an AOA issue, which is addressed by reducing the AOA.
The algorithm used at the time of the AF 447 accident is incorrect; it has contributed to the Stall. Airbus has recognized the need for corrections.

There is also another thing you may want to come to terms and recognize. It is the importance of a "direct information transfer" between the PF and PNF regarding the position, and actions on the side stick.

Perhaps there is a need for a call onto the computer/software expertise, which you've mentioned on a number of occasions, which should be of help in recognizing the qualitative difference between "direct" and "indirect" "information transfer".
