Well,
I'm no authority but here's a useful link discussing some of it.

I'd no idea such things existed until my recent re-edits of some favorite novels, where I encountered them, having initially assumed they were serial em-dashes. Both 2 em-dash and 3 em-dash are preferred to a string of em-dashes, since the latter could be broken by a line break and display weirdly. This same author displays a marked penchant for the em-dash, so that he would on occasion use the uncommon 2 & 3 em-dash is perhaps not surprising.
