Sometimes they will return borrowed points.
I was going to have them switch out points between reservation, so that I could bank current UY points.
I had a waitlist that didn't come through and I decided I would rather pay cash for one night than switch resorts twice.
My first two nights were current year points, the third and fourth were borrowed points.
My third night was at a different resort. waitlisted for the same.
I canceled my third night at 31 days out.
A CM that I spoke with earlier told me about being able to swap out the points.
When I ask them to do it when I canceled the reservation, they put me on hold.
The CM returned and told me they decided it was easier to just put the points back in their own UY instead of swapping out points.
I have no idea why they did this...

But I guess anything is possible.
