Having camera lock-on allows you to "strafe" around the target mob in a circular pattern when using your directional keys. Extremely useful for melee DD for avoiding accidentally facing away from the target when moving around and also saves you from readjusting your camera angles to keep your character faced correctly towards the target. The drawback of course is that you can't tab-target other enemies when locked on to one.

He wants the utility of being able to strafe around and faced towards the locked target but still be able to change targets with the tab button. I think that explains it.
