It doesn't make any difference here, Drain. The point of that function on retail was to avoid people rolling both sides on a PvP server to shit talk or 'cause drama over in-game. And also to avoid spying on other faction members with level 1s and /who commands, whispers, etc. It could also have been to avoid certain trading between factions and probably more things I'm forgetting right now.
However, in private servers you can already make as many accounts as you want, so it doesn't make any difference whether you allow both horde and alliance on the same account or not. As everyone will create secondary accounts anyways for bankers or other faction members to spy on other faction or whatever foul tactics you employ. :p
