What was being said was that the entire projector housing was moving up and down to form the low and high beams. That is not the case. There is only one moving part (well, two if you count the solenoid itself), and that is the shutter. It's on the bottom of the housing because the light beam is inverted as it passes the front lens.
Ok, well this is the impression I was under all along...
