I'm not pushing back...just trying to understand the wording above.

The "and" in that sentence seems to indicate that the manufacturer has
the final say. In other words, the NEC requirement is based on 2
criteria: location and the manufacturer's requirement.

The NEC requirement is just the general one that equipment be
installed according to manufacturer's requirements. Manufacturers
typically say that their fans may be installed over showers if they
are installed on a GFCI. I don't know if there are any that allow
installation over a shower without GFCI protection.
