My B&S P2200 portable inverter gen manual says, "--the AC stator winding is isolated from the grounding fastener and the AC receptacle ground pins. On a floating neutral generator the AC receptacle ground pins are not functional. Electrical devices, such as a GFCI, requiring a functioning ground pin will not operate."
That says nothing about the ground pin being isolated from the grounding fastener; those are indeed tied together. It's just saying (in a rather confusing, roundabout way) that the neutral--the stator winding--is not bonded to the two ground connections, but rather isolated from them.
I have no idea why they suggest a GFCI requires a functioning ground pin to operate. A GFCI specifically does not need a ground to operate. In fact, using a GFCI is one acceptable way, I think the only one permitted by the NEC, to install a receptacle accepting a three-prong grounded plug in an ungrounded two-wire AC branch circuit.
