I don't see anything damning in this clip and I took a quick glance at the vod and also couldn't find anything out of the ordinary. This guy is pretty high mmr if I'm recognizing the people he's playing with, I think he's just good at tracking. Not to say he isn't cheating, I just don't think this is what proves it. The discord has a channel to report players for further review, post in there and it'll get looked at for you.
