What if you have 2 identical hides and he doesn't like either one of them? That would be even more stressful.
For all I know you could have a less safe feeling hide on the cool side, so the BP has no choice but to use the warm hide even if its bigger it could feel more secure than the cool side, and again this is stopping thermo regulation.
