You mean from tipping forward (over the handlebars?)
We don't know what the kinematics of that shock are, but one of the interesting consequences could be that longitudinal impact actually causes vertical travel. In other words, hit a death cookie that punches your ski back, and get lower to the ski as a result.
that could be the case but rapid deceleration could be a bitch . Objects in motion tend to stay in motion, energy is neither destroyed or created, its just re-directed. look at the hinges, the only way to go lower is to move forward, and the lower instep strap creates quite the leverage/hinge point for the upper body.. I guess if your shock is damp enough, it could minimize this but I'm doubting that. .
