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.
Yes, but wouldn't a slight bump or even wind topple the bike without a locking crank? It does not appear stable enough to trust a carbon bike with.
