He doesn't have the free brain cells to realize that his wing problem is correctable by the rudder, a different control surface.
Good post. I've got an impression that there will have been a very disturbed airflow over the rudder, and with the AoA and the existing RTLU limitations, the +/-7.9° available may not be effective. We certainly don't know if the rudder was used, but if it was, the BEA must have seen nothing significant in its use, not to mention it.
