Paul,
410-57(c). Reading that one, I would go along with your interpretation, as the only other way to read it that I can see is to just prohibit the installation of a receptacle inside the tub or shower-stall itself. And nobody could be THAT stupid, right?
You wouldn't think that anyone would be that stupid, but as I recall, the substatiation for the proposal was "there is no code rule preventing the installation of a receptacle in the shower stall or the footprint of the tub!! I'll try to look up the exact statement later this weekend.
Don
