Spiral indicated in white.
Pink/green boundary's indicated in yellow. Parallel lines.
The one line at an angle is illustrated in blue, Which is pitched in the opposite direction to the claimed angled ramp.
I see no correlation at all between the white spiral lines and the pink/green boundary lines.
If we eliminate the phantom white line spiral altogether, it becomes even more evident.
