No, this is not a 'zomg my alts keep running, how do I make it stop!' question.

I was wondering if there is any way to consistently make your alts orbit. I.e. Run while on follow of you, so they run circles around you.

I've seen it happen a few times, but I don't really understand why / how it happens, but I'd like to reproduce it, cuz it looks cool, lol.
