Sure, but why is that wire less susceptible to a short than a wire not
feeding a motor? If the OCD is there to protect the wire, it doesn't
matter what fails on the other end of it.

It isn't, but a short is by definition a high-current event so the size
of the breaker is essentially immaterial.


That's not my point. Forget the motor operation. What happens when
it, or the outlet itself, shorts?


Au contraire, IS the point and why there's a difference in NEC for
dedicated motor circuit...


OK, why? The fault that the OCD is there to safe is still there.
