I collected some points into the gifs,you might expect the similar action to happen in through all that video. The gifs are slowed down to 0.25 speed making it a very remarkable feat to perform such lock on's.

I suspect him of using an aimbot. He also has some interesting anomalies,like performing of these two rounds might indicate:
