On my BMR it clamped to the housing then the ends were connected to spherical links attached to the frame. The rear end itself doesn't move around, I think what's happening is if the left corner of the chassis goes down like in a turn it'll push the bar slightly to the right and vice versa. It doesn't move that much but would leave a grease mark on the bar like the OP's. When driving straight it wouldn't move at all side to side.
