I don't see it in the first demo.

The only real questionable spot was the para firing at around 1800 if you use SHIFT+F2. Goto 1800, slow down to 30-40% speed and watch him fire at me and Lukey. The fire on Lukey being the oddest, with the mouse jittering a bit in a tight group.

Rest of the time, he was using AK a lot, and AKs are infamous for easy headshots.

The second demo has a lot more questionable spots, and I stopped at a point because it became consistent but here are some frames to put into SHIFT+F2.

16000
20000
22300
30500
34000

He has recoil and not using an aimbot per-say, but his cross-hairs go down with the spread so his shots are still going towards the person. It's a little too even and controlled, and wasn't happening on the previous map (except during the para incident mentioned above). In fact, it doesn't happen on Italy until around 16000 when he pauses several times at the start of a round.

Could be an anti-recoil script. Doesn't stop the recoil but pitches down your cross-hairs on consecutive shots to send the bullets to the same general area. I've seen them before back in my pub days 3-4 years ago. Horndog's is the most used.
