Sorry I'm being dense, but when you say "they would keep their UY and resort", are you referring to the calendar year use year (e.g. 2012 vs. 2013)? If so, then I think I understand -- the banking deadlines would be based on my October deadlines rather than their old February deadlines. So, if I received a transfer of current february UY points (2012), they would be put into my October 2012 UY and I couldn't use them to, say, book a vacation in August, 2012, even though as original February 2012 UY points, they could have been used for that time? But if they went into my October 2012 UY account, wouldn't they be ripe (e.g. no banking necessary) for a March 2013 vacation?
If the points "would keep their UY [i.e. february] and resort," then I think I'm confused again, because it would seem that if they went into my Oct UY, they couldn't keep their Feb. UY characteristics. I guess I don't know what those points being "put into your 2012 UY" means in that instance.
