bah, nvm, I see the big conflict.

Keep in mind they mean for a CROSS to have a vertical projection, e.g. from a bounce or from launching it. No matter how I twist this in my head it seems the grey area is whether or not the "vertical projection" must happen before the trackball breaks the plane of the finish line or if it is still scorable to give the ball a vertical projection after it breaks the plane but before it has fulled CROSSED.
