They're either having to have to have a way to change your race on the same side (IE, $25 to go from gnome mage to human mage) or prevent you from doing a double faction transfer to switch races.
They appeared to say that you will have a choice of which race to select when you do the switch (limited by your class, obviously), but that you will not have the option to change your race under other circumstances (ie, if you want to change from tauren to undead or gnome to human). I figure that they're saving that for later. If you switch factions and then switch back, you can only switch back to your original race.

Of course, they haven't finalized it, so this could all change. But they updated the initial post to answer the flood of questions people were posting.
