It's a kind of squeeze. The real goal is to make sure your enemy takes only one path, the path you have planned for them. Every time the enemy veers off their designated pathway, White Hats release a proof. They always release the least amount required for this at every point.

This can look frustrating to us, but in reality it shows their power level. Just like a Japanese Samurai master who moves just ever so lightly in a sword fight and never uses more power than necessary (until the final blow), it shows deep understanding of the weapons being wielded.
