if the region is marked as unconditionally belonging to either black or white, then black and white are forbidden to play inside the region.
In the case we discussed, if both false eyes are identified as unconditional eye, then it cannot be filled. So no side will play inside in it. If a program has less blunder to fill eye, that definitely reduce the playout length.
