It's a function of the torque converter, which is the auto-tranny version of the clutch and pressure plate in a manual. It is basically a hydraulic coupling device--the auto tranny is never completely disconnected from the engine (as a mechanical clutch does in a manual), it is still spinning even when the car is at idle and stopped, and generating some torque from the circulation of the fluid inside, which is transmitted through the gears to the wheels (if the car is not in neutral). Depending on its "stall speed" setting, this "residual torque" may be enough to hold the car in place on a slight hill, or creep forward on the level if no brake is applied.
