I think a more logical rule would be this one...foot down, cut up; foot up, cut down.
The guy in our guild presentation said it had to do with the way the thread plys are twisted together---they are designed to glide smoothly in the direction from spool to needle; but when pulled 'backward' up through the tension discs that small bits of the thread gets shredded off and will eventually cause problems. News to me!
