Evolving slalom technique?

I'm not sure I'll get up at 5 am every time and watch many ski world cups this winter, but I stumbled out of bed today to watch the 2nd run of the Levi men's slalom. Norway's Henrik Kristoffersen, won magisterially and my take-away, after watching the incredible new breed of Swede and Norwegian slalom specialists, was their peculiar style in which their hands appeared to be totally free in relation to their feet. 

Let me explain; for years, skiers' arms appeared to trigger their foot work and both arms and legs operated in perfect synchronicity. The Scandinavian top slalom racers seem to have broken away from this regimented rhythm and their arms appear clearly free and independent from their feet. A much freer impression emanates from their skiing style, in which the arms are following the motion, when in the past, they seemed to have been the action's catalyst.

Have you noticed it? Do you agree?
