Add me to the list of people that know this is not true.
The top of the head tube is being cut to fit inside the top and bottom crowns. The frame position does not change. The distance between the lower clamp and the ground has not changed. The lower clamp on this lefty is fixed to the fork, so if the lower clamp goes up as you say, then the front wheel is magically levitating off the ground.
Experience is a great teacher, but successfully completing high school geometry can be helpful too.
