The thing is, if you watch the video it doesn't even look like he's being aggressive. It looks like every other video you see of Paul, placing a few shots and crushing discs along tight lines. During the -14 round he birdied 9 (which he took a 7 on this time), eagled 10 (took a 4 today with another OB drive) and birdied 16 (went OB with his pink Destroyer and made the putt to save par). Those three holes are the difference between the -14 he shot yesterday and the -7 he shot today. I'd bet money that if he had taken a 4 on hole 9 and not a 7 he'd have at least birdied 10 because the weight of the previous hole wouldn't have been as bad.
With that said, McBeth was probably 3 mistakes away from carding another double digit under round and having a 10 stroke lead on the entire field. This tournament is his to throw away, which isn't going to happen. Only one other player has carded -10 or better so far and that was Patrick Brown while McBeast is averaging -10.5. He's on another level right now, even on his bad days.
