The first rollout here is the genuine article with XG correctly doubling after either play.
The second rollout is using the rollouut for double and no double setting. The results there from either move come from it indeed doubling. The difference is that the play is made entirly on the assumption that the cube wasn't sent. In this case that makes such a huge difference that it actually shows what is the best play to be a whopper.
