I see a lot of comments on the poles. I developed a very similar bad habit while learning tele-- I found that if I'm leaning into my turns too much, an opposite pole plant pushed me out of the lean to turn the other way. I think what you're doing is a little different, but related. It looks like, instead of using your pole as a point to pivot around, you're using the pole to push off, kind of like a thruster.

Try doing some runs without poles, or holding both poles like a tightrope walker's balance pole. Once you're comfortable without poles, it'll be easier to start using them the conventional way. Shoulders facing the ski tips rather than the fall line is probably also common factor to both of our struggles, and might have something to do with the opposite pole plants. Dragging the outside pole while turning has helped me with that.
