Housing balls together?

[Rob]

And how, without a shred of doubt, do you know this?

Pure speculation. I have no idea what most of my snakes think most of the time and I've been doing this for a really long time.

Here we go again with you defending housing together. Sorry I'm just not jumping on the bandwagon of thinking this is a good idea. If while in the wild where they have a choice of how to live, they huddled up together I would say you have an argument. But they are solitary animals. I'm not just regurgitating common practice, as I often do things that aren't by the book. But on this particular topic I feel it adds stress and risk I don't feel is necessary.
