As long as the player doesn't sway off the ball and then have trouble getting their weight forward at impact. If a student of mine manages to get most of their weight back over their left leg at impact despite doing this, I leave it. If my student does this and then tends to hang back during impact, I ask them to stablise the knee. Obviously, this doesn't automatically solve the issue but helps give the student a feeling of staying move centered during the backswing.
