Now you are talking about Tai Chi Skiing; Tai Chi Skiing, given the Tai Chi terminology, is "rooted on the skis/feet," "controlled at the waist," and "manifested on the hands."
"Rooted on the skis/feet," so in balancing the gravity, the body must also absorb the reaction force from the gravity, and the body does it by moving the weight/CM around, guess that's what you mean by "circumduction." "Controlled at the waist" is to say, using the two big back muscles (located just outside of where kidneys are) to move the hips to move Dan-Tian/CM to move the legs... While the shoulders are kept steady facing the fall-line, the rotation is done by moving the hips against the shoulders. The shoulders balance the force by redirect it, through the arms, and release it on the hands, "manifested on the hands."
Ps Oops, back to the topic, as for wide stance? It's good for setting up edges fast, but I like the "circumduction"'s fluidity.
