This is the split path in THZ2, where one path is the turret puzzle and the other is the sequence of conveyors that goes through crushers.
The near half of the first conveyor slows you down as you pass over it in the direction that it's supposed to be moving. It's hard (but possible) to detect the effect if you're running on it, but if you roll onto it you get slowed to a halt in just a couple of seconds. Once it stops your roll, it does push you along, but at a fraction of the speed it should do. If you roll along it in the opposite direction, it doesn't impede you at all.
