/faceCombatTarget faces previous target, not the current one

I created a hotkey that looks like this:

/faceCombatTarget
/attack

After I kill the monster, loot it, target another one, press the hotkey, my warrior turns and faces the one I just finished looting instead on the current target.

So, I modifed my hotkey to look like this:

/faceCombatTarget
/faceCombatTarget
/attack

Now, he turns to face the previous target, then turns to face my current target, then attacks.

If I am already facing the curent target, he swings around to the previous one, then swings back to the current target. I am getting a little dizzy after see this all night.

Is this a known problem ?
I have my hot key set up like this, so I can turn and face the monsters when they run around to my backside.
