That drawing is misleading IMO. Each straight(er) edge of the aperture causes a diffraction spike that has two points/sides in the resulting image. I relabeled the first half to hopefully make it clearer (the asterisked numbers indicate the edge that caused the spike). In the second half I labeled the spike originations in matching colors.
