I am always lead on my reservations until we finalize the guests. The problem will come in when you check in as you can only be an official guest of one of the rooms.
But if you mean to just book that way for now, it’s not an issue
One year, staying on points, we had the whole party registered for two separate DVC rooms (one at BC, one at OKW) and it worked fine... we just needed two different 'leads' for each of the rooms.
