I think the reality is that we all carve for our own enjoyment. If we happen to not look cool, I don't think many of us care; we're too busy enjoying the sensation of rocketing across the mountain on an edge.
However, I also think that in many cases the technique that happens to look 'more cool' will also provide a slightly more awesome sensation.
Whatever the case may be, the way Patrice and Jacques lay out full carves is, in my opinion, pure style.
