Yes, the under new rules it's a penalty and a restart if it goes partially over.
It is an instant DQ still for all the way over, but that is clearly not what happened. You can see at 0:25. Although the reap is tough to see, what is clearly in the video is the far side from the reap, and there is clearly no foot hooking there or passing that line.
So at most it could have been a partial reap that crosses the centerline but does not go all the way over. The treatment for that is a penalty and a restart.
The only exception is if the ref saw a submission hold, which I sure don't see. That's why I thought maybe the guy tapped because they both stop and he says something to the ref. But I don't see a tap (could have been verbal too) so no idea if that occurred or the ref just completely wrecked the rules on this one.
Either way, bulllllllllllllllllllshittttttttt.
