If they are the same species and subspecies, then they are not hybrids. That doesn't mean they are pure blooded either. Many people in the boa world would consider them mutts. It would be no different then crossing a cornsnake from Florida with a cornsnake from North Carolina. They are two completely different populations with different looks, but the same species.
There are probably as many people who are as passionate about locality pure animals as there are people who are passionate about hybrids. I see them as two extreme ends of the snake keeping hobby as a whole.
