Why teach students how to move from one undesirable out of position scenario

to be useful in real flying? It makes no sense to me.

The 4 corners of the box are where one will be to initiate a steering turn in high and low tow.

Flying a smooth box with a pause at each corner allows the student to practice and demonstrate mastery of flying on tow.

Drop into the wake then move to the side until the ride smooths out. Turns out it's not very far and puts minimal strain on the tow pilot's foot.

Again, boxing the wake is to be a demonstration of precise control of the sailplane on tow, it's not something to be rushed.
