I suspect very rarely, for the good reasons you have stated. If it did happen, it was just a case of “showing off”. Good teachers don’t need such melodramatic acting to prove they are in command. You can cane and slipper effectively without needing any exaggerated movements.
Equally unlikely is the business of bringing the vaulting horse into the centre of the gym. Why waste precious minutes of a lesson on an ego trip like that, when the matter could be dealt with at a later time?
