No matter what, the points that have been given are good ones. If one of them gets sick, it may spread to the other. And then, like stated before, who's poop is who's?
And in regards to you saying that there are huge amounts of pythons in the same termite mound. I'd like to see some information on that. So far when I look up density of royal pythons, all I get is that document.
If there's something else that says different, I'd like to know.
