That sounds ridiculous! My snake loves when I bring him to my friends I just put him in with his ball and they just bundle up in the big hide. When I bought him from my local breeder both me and my friend got both of our snakes at the same time, from the same tank, they were both together and both are doing fine no problems whatsoever.
The sharing of the hide is either dominance or done out of necessity for security, not out of friendship. Snakes are solitary creatures and don't need play dates...
