That's not the PoV trap, since from their perspective, they are right about the Seanchan having the same accent. It's like the distinction between a Southern accent and a Creole vs Georgia accent.

The PoV trap is where a reader is misled by taking a character's opinion for fact. This is more of a case of Mat's Aiel girlfriend calling him short, when he's on the upper side of average.
