I guess it's a question of whether or not this is a permanent housing situation. If it's just a temporary breeding arrangement and the other male is in there to influence the other, like you suggested, and removed when he is not present to supervise, than im sure there is no major harm being done. But don't quote me, I'm still learning myself.
Also to the OP, I noticed in your signature you have 2 of your snakes listed as "super normal." If I may, what do you mean by that? Are they just that normal looking?
