Why else would the NEC allow for the use of a 3 prong outlet on an

into it?

Well, 406.3(B) of the 2008 NEC states: "Receptacles and cord
connectors that have equipment grounding conductor contacts shall have
those contacts connected to an equipment grounding conductor". And
406.3(D), the section that deals with using GFCIs on circuits without
equipment ground, does not appear to override 406.3(B). So I agree
the situation is confusing and the intent is not clear.
