Well first things first, can't prove anything about bhop macro/script without showkeys enabled.
In terms of the cheating, I really can't see anything out of the ordinary in your demo. Niels is a very old and experienced player and looking at his stats they are fairly decent but nothing too far from the average.
Were there any specific points in your demo I should look over more closely which look "fishy" to you? Cause right now I'm not really seeing much in the way of cheats
