I believe that Jon Z. was pointing out that the K-Line didn't know which direction was being commanded as it could miss a direction change. With the PWM, there is no doubt as to which direction the R2(4)LC is commanding you to go. It could be that just the presence of the PWM on one of the inputs simply triggers the direction and the actual motor drive is generated elsewhere.
