I can't say for sure, but since the only use of the AO object is providing a secondary UV map, it makes sense that only UV coordinates are read from file. All the other information should be ignored. It is also my understanding that TDW's GR2 importer assumes faces in the AO object being in the same order as in the main object. Thence the buggy AO mapping if face order is not exactly the same in the two objects.
I know 3dsMax supports multiple UV sets for the same object. This is the best way to ensure that, once exported, main and AO objects are identical in all the respects but UV coordinates, and I bet devs exploited this feature to ease their job.
