I'm not seeing any issues (not saying they're not there though), just
reporting an apparent inconsistency.

This is indeed the assignment Pavel Shirshov changed. It seems obvious
(on the surface) that if you're still using Is_Bg_BGR it should be
assigned here, or at least that this was the original intention of the
author. But you are probably a better judge of that ;) .
