UpStream, ArcPoint and DownStream points define the main circle of the rotary conveyor.
The Upstream and DownStream pair of points separate the circle in two arcs. The ArcPoint defines the arc that will be actually used. The one to which the ArcPoint belongs will be the movement path, while its direction is determined by the UpStream - DownStream points pair, with motion starting from the UpStream point and ending at the DownStream. So the working window is always from UpStream to the DownStream moving through the ArcPoint regardless of the resulting angular direction (CW or CCW).
