When you first watch your lesson, you might think, "You want me to do what!?". Once beyond your initial surprise, you’ll find this to be a very useful exercise to develop foot and ski control for ungroomed snow, bump, and crud skiing. Since you’re already making short turns and using your poles, the glove squeeze will help you learn to keep the skis and legs lined up correctly. In ungroomed conditions, especially powder, crud, and windpack, it’s crucial that the skis and legs work and stay together. When the skis come apart, they will invariably head in different directions, perhaps crossing, perhaps diverging, often leading to a tumble.
