A head shot is a head shot, back of the head (which is harder to hit obviously), or front of the head. You shoot someone in the head, you do more damage, simple as that. You melee someone in the back, they die. It's not that complicated actually. The one hit in the back kill melee is a balance in gameplay that works very well, and rewards you for either sneaking up on someone, or figuring how to get behind them with a quick kill.
