wait... what?! Why the hell am I riding that thing horde side?!

I have NEVER bought that on any of my horde toons! Never managed to get THAT much money and none of them is Exalted with the Kirin Tor to lower the price! So I decide to check my mount list, and I see some new mounts there. From what I saw apparently some of them are now being transfered to their other faction equivalent. Things like the mounts sold by Mei Francis in Dalaran, the Hodir mammoths, I think the Silver Covenent <> Sunreaver ones do also, because I did buy the dragonhawk but I'm pretty sure I never bought the hawkstrider and I have it now, same goes with the Tol Barad ghost mounts since I saw the drake was on both sides before the patch but I'm sure I never bought the wolf, the motorcycles (woohoo!), and to my big surprise, the Alterac Valley mounts as well as the Black War Bear for killing the factions leaders! The normal PvP black mounts aren't transfering over though, so I guess it's the ones that have doubles of and some related to achievements.
This also might explain why some people get a mount and their counter goes to 49, 99, and 149, and then they get the achievement for 50, 100 and 150 mounts. Might be they already had, or just bought, a mount that has a double on the other faction, and the game counts them as two separate mounts. Another thing worth testing since I can't do it, would the lion and scorpion mounts need to be bought just once and you get both? Neither guilds I'm in are lvl 25 because both are real life friends only, so at most we're only 5 online max.
This appear to be a stealth change, because I don't remember seeing that in the patch notes at all. Not that I mind though.
