I had logged a bug on this. I can't find it anymore. It was stuck in NEEDS MORE INFO for awhile and then even after I posted more replays they didn't do anything with it.
The problem as far as I could tell was that when someone drops into a Deep Middle zone, if no one enters his zone by a certain time, he just bails out deep, even if no receivers are running deep routes. This can cause him to miss a guy who runs right to the middle of his zone afterward. The replay in the OP looks like exactly the same issue I was trying to get them to fix.
