What probably happened in your case is that a VWL member decided to trade their points for a non-DVC stay, then their points revert to Disney and they then rent the room out to recoup their costs in providing the non-DVC stay. Any DVC room booked on cash prior to 60 days before arrival is obtained in this way. Starting at 60 days out, the rooms in the DVC inventory, can be rented out for cash through Disney. Disney does own a VERY small percentage for their own use, which is where some of the cash ressies come from. But with that small percentage and the lack of concierge units, Disney would probably never allow concierge villas to be booked on cash, and risk the wrath of owners! BCV is a perfect example of this, there are VERY few 2 bedroom dedicated units with two queen beds in the second bedroom, these units can only be reserved by DVC members and are almost always scooped up by BCV members before the 7 month window opens up.
