If you're referring to the ACC pedal kickstand, note that the crank arm in the photo is positioned a few degrees behind bottom dead center. That's all that's needed for the ACC pedal kickstand to work.
It's the same principle as standing a bike upright by positioning one pedal so that it's (1) rotated down and slightly back from bottom dead center and (2) resting on a curb. Many of us learned to do that for decades. The ACC pedal kickstand just eliminates the need to use a curb.
