Sent this video out to a number of varsity officials and most agreed that this was not helping the runner.  The case can made that the blockers are just pushing the pile forward and not the runner directly. 
To be honest, a couple of them thought it was.  What I always tell the offense is that they can push the pile forward, push the blockers forward, push the defense forward but they cannot push the runner directly forward. 
I tried to attach the video to the post but it says the file is too large - here is a dropbox link to it:  https://www.dropbox.com/sh/dmvhfwjy4l9k9pl/AABa13vrxrf4phwLoE08-U3pa?dl=0

Let me know if that doesn't work.
