Does a Rotary Phase Converter Actually Make REAL 3-Phase Power? (120 Degrees)

Does a rotary phase converter produce real 3-phase power? Real 3-phase power has its three phases offset by 120 degrees, but a rotary phase converter passes through the two 180-degree input phases, so how can it possibly make real 3-phase power? In this video, we'll throw a scope on the output of my American Rotary AD-5 and confirm that yes, it does, and we'll talk about how.
