I'm a noob at Supcom but have watched a lot of replays in the last months. To me it looks like he has pretty good unit micro but lets his economy suffer a bit. I wouldn't be surprised if he came from a game like CoH which has less emphasis on base building. The expectation then would be that he would do well on maps without a lot of upgrading like this map or Theta. I haven't looked at his stats thanks to GPG being MIA, maybe I'm wrong
