@LiquidFeet will have to answer, but no. As i understand, your left foot is downhill, on the little toe edge sliding down. So if it was steepish,
an observer downhill would not see the base of the ski.
Me thinks one is still mostly on the uphill edge, big toe, or at most flat. Though on a very gentle slope with firm snow, maybe. Call me dubious, but the definition may be different. For example, a downhill foot,
one footed release to little toe.
That usually goes into a turn, which takes awhile, not a straight slide. slide.
