I know that with the front wipers if they get stuck then they will stay powered to finish the full range motion even if you turn them off on the stalk. For example, it snowed the other day and I tried to use the wipers to remove the snow from the windshield but they couldn't really move very far and they got stuck. I immediately turned the wipers off and cleared the snow/ice from the cowl and windshield. As soon as I cleaned enough snow/ice from the wipers so they could move, the wipers finished a full range cycle. So in theory, if the rear wiper motor had gotten stuck when you tried to use them and you never fixed it (by greasing the motor shaft) then it could still be trying to finish the motion which would in turn drain the battery when the vehicle is off.
I don't know if the rear wipers are the same as the front, so this is just all a theory. I could be way off though.
