It's because the hole ski stands out from the rest due to
its lower mass inertia moment. Thanks to this reduction in
weight at the ski tip and tail, the mass is concentrated on
the centre of the ski. The positive effects are a considerable
improvement to ski oscillation and, as a result, optimised,
smooth running and better turning and control.
