If you have xenon, then there must be a self-levelling system installed (at least in European countries) to avoid blinding others. This is the "move up and down" motion the dealer told you. This is standard on all xenon lights.
Now, the adaptive headlights feature is the option of implementing the left/right movement of the lights depending speed and steering wheel angle. You can easy check it by moving your steering wheel while parked against a wall; the lights will slightly move left-right. This movement is larger while driving.
