And in that situation, they would say no. However, consider a couple of scenarios and assume you've already transferred points for another trip between two contracts. One situation where you have a few orphaned points that you can't bank or otherwise want to use and the other where you want to do an exchange or cruise. Many of the exchange options require all your points be in ONE contract to do so, what if you wanted to do a 10/11 day cruise for a family of 4 and had 3 separate contracts. You don't really care whether they take 300 from each of the 3 or 900 all from one (as an example), but
DVC does. So to make it happen, the only way to get by this technical barrier is to do a transfer. Many times in the past they didn't even say it was a transfer, just that they would take care of it and they did.
In the past and on a case by case basis, DVC has bent the rules when it seemed appropriate. As I noted, they have transferred banked and borrowed points and allowed more than one "transfer" when it was obviously reasonable to do so and when the rule was only one transfer. I have an email somewhere from a few years ago that specifically states they have "significant flexibility when it comes to multiple contracts of a single owner", I'll have to look for it when I get a change. BTW, some points timeshares combine multiple contracts under one membership even when there are different home resorts AND use years. So this is a problem created in part by how DVC has segregated the ownerships.
So, IMO, we won't truly have the answer until someone who is knowledgeable enough to word things the right way is actually denied making a reservation that fits into this arena due to the transfer rules. We shall see.
