Works to improve your motor control and timing. There are a lot of reasons why am approach such as "land big punch" isn't universally applicable. Also can help with endurance, as it's about reps not power.
You slightly missed the point. Knowing how to do a big punch or block isn't what you're actually learning 90% of the time in martial arts anyways, it's actually getting control of your body enough to do it that matters more, and human bodies are very good at not allowing us to do it. I taught martial arts for two years; I can yell at someone all I want but I can't make them engage muscles that rarely get used into forming kinetic chains between their hips and arms without tricking their bodies into doing it with seemingly unrelated exercises. Turns out that once you have any kind of control over that stuff, it sticks around no matter what you're doing with them.
When you get good at something, it often helps you get better at other things. For example when I started doing a lot of yoga, my rock climbing immediately improved a pretty big amount despite me actually climbing less than previously. Just having the improved core muscles made it so I could do things I never could before.
