The "foggy" part of this to me is the 10-2 part of the rule. The defender is running almost 90 deg toward the sideline but his upper body is facing toward the goal line as he is tracking the runner (IMO he never really turns). If the 10-2 applies to the players upper body it's OK, but the actual contact is from the side and outside the 10-2 as well as below the waist. I also don't believe that the initial hand contact has any rule impact here since the blocker was committed to a low block the entire time and the hand contact played no part in the result.
I still believe that based on the clear intent of the original rule change language and examples that this block is legal.
