As his upper body rotates upwards the reach would have to be shortened accordingly. If you imagine Gordon rotating his pelvis and torso to a lower position you can see how it would necessitate a increased reach to his arm supports with a corresponding decrease in stack and increase in reach (top tube length or stem).

Make sense?
