I believe the problem existes because (as far as i know) BP's don't have any codominant morphs. Snake keepers never had to make the distinction between codominant and incomplete dominant. When someone first used the term codominant it got stuck in people's minds.
I'll rephrase that there are quite a few at least on this forum that understand the difference between the two. Also I agree that old habits are hard to break and people just use co dom out of habit.
