The sticking point
I'm wondering how the wit of the pilot who has got themselves into a stall, or nearly so, would be so quick of mind and exacting as to stare inside and position the stick or column to a remembered position, 'central' or otherwise! Indeed the forces on the controls will not be symetrical and will mislead.
The very good reason to deal with the angle of bank secondary to unstalling and conserving height is that the stall is the problem not turn, indeed from shallow angles of bank many aircraft at the onset of stall will quickly flick or at least roll very rapidly the other way. If the unpracticed pilot is not already completely out of their depth they will now, very quickly, become so.
During the turn the ab-initio student in particular and many infrequent flyers will look sideways across the nose and in doing so believe the nose has lowered in pitch and pull back (pitch up). It makes good sense to first recover the aircraft and then consider the angle of bank.
