Yes. Not harping on you, but to explain further: this stresses BP since they are solitary animals past a certain stage and rather than being able to cohabitate as a group like some other species of pets (cats, dogs, some rodents, some fish, etc) they are solitary. Thus, two snakes -- even related, or the same gender -- will compete with one another for ideal resources such as hides, heat, specific safe locations, and so on. This brings unneeded stress into the animal's life -- which given how prone BP are to go off feed -- ends in (best case) a snake going off feed or (worse case) attacking the other snake during mealtime or engaging in ophiophagy to remove the competition. Which means a dead snake, since they're not intended for such size or composition in their meals.
Breeding or freshly hatched is essentially the only time BPs should ever be housed together, and even those should be for a limited time. Ultimately, it's better for each snake's health to be alone in its enclosure. There's no concern of them getting "lonely" or anything like that.
