Nm is allowed to enter an outside disconnect and any wiring that is acceptable in Chapter 3 is allowed to be used to wire a pool pump for a single family dwelling. I think the reasoning is that the nm if installed properly is protected within the dwelling. This makes little sense, however when you see that it is not allowed for the pool lights. The difference is that the pool light is in the water and close to where one would swim and possibly come in contact with the light should the egc get damaged.
The difference is that the ground wire for a pool light must be insulated and installed in conduit. Nm to the pump is fine. I have not heard of an inspector turning down a job as long as the NM exited the house and stopped immediately at the disconnect. It cannot go thru a conduit then to a disc.
