I would make the following comment:
All stalls are caused by angle of attack - I think we can agree that!
The difference between the high speed stall and the traditional low speed one is caused by the mach number. At high mach numbers the angle of attack at which the wing stalls is much reduced.
With a commercial airliner being operated inside its certificated speed envelope the only way to get to the high speed stall angle of attack (even though it is reduced by the mach number) is to manoeuvre.
