No, the leveling function is based on the difference in ride height between the front and the rear.
When you have a trunk full of cargo or 3 people in the back seat, or both, the rear of the vehicle sits lower due to the load. Towing is the other example but doesn't apply so often to the F30 as with SUVs etc.
In that situation with static headlights, the light would be projected upward and potentially blind oncoming traffic. The leveler system detects the difference by keeping tabs on suspension travel and adjusts the beam angle to compensate accordingly.
I don't know for sure but I believe the adjustment is not fast enough to account for dips in the road. If you are going up a very steep hill, perhaps there will be enough squat to cause adjustment, but again it just comes down to a difference in front/rear ride height.
