When Did This Rule Go Into Effect

Look at CB play 9.2.3 Sit A:

Here's the important stuff from 9.2.3.A: A defender may legally contact an eligible receiver beyond the neutral zone before the pass is in flight. The contact may be a block or warding off the opponent who is attempting to block by pushing or pulling him. However, if the receiver is not attempting to block or has gone past or is moving away, it is illegal for the defender to use hands in the manner described. In this situation, it is clear that A1 is no longer a potential blocker on B1. (2-3-5a; 7-5-7)

If the receiver is not attempting to block I don't see how a defender can legally contact that receiver "all the way down the field".
