I dont know about Edwin and his swing, but in trying out the SF 9-3 type swing on the range, when I do full swings I feel a little extra pressure on my right knee (Lefthanded)... the reverseK, at least to me, putts extra weight on the right knee... then with downswing it supports most of the body weight and add in alot of rotation on top of the knee on the follow through. Back felt good though.... I would bet that many agressive, 100% power, driver swings would ruin my knee
