Would you not agree?
Very little pivoting ( or none ) would require no pole plant. Most GS photo bursts on the Ron Lemaster site will verify.
For high end SL skiing, pivotting (aka turning the feet) is a certainty. And yes, the intent will dictate pole timing is key, as ssh says:

The blocking plant will for sure be a fulcrum, and I agree that the plant MAY be done earlier, but that is not the move I would teach someone that asks: "How/when do I plant the poles?".
In such a case, the usual goal is to stop the upper body from rotating. Hence, plant where the skis are flat so that the pivot is easier, and does not require such a big move to get to the other edges.
From what I see, most folks err on the side of the early plant, because they want to get from one edge to the next as quickly as possible. As a consequence, they have no real neutral position, and don't learn how to rotate the legs; they launch a turn rotating their full body instead.
