Okay, I can see where the confusion sets in. You have a sw-cursor which is
causing rendering during the process of swapping over the buffer names - and so
the names do not match up afterwards.

Hmm. I've added some more debug to get to the bottom of the sw cursor issue and
whilst you capture that, I'll try and fix the confusion with the sw cursor
getting in the way of the buffer exchange.
