Think of the path as everything between origin, and destination. The path of the flow changes, but the origin and destination do not switch. It goes from the same place to the same place, but leaves and arrives by different paths. In a solid circuit the path never changes.
You can't change origin and destination without switching polarity with either DC or AC. The four wires from the SDC power supply allow changing both origin and destination without switching polarity.
Its not AC because anode, and Cathode never switch, and its not DC because origin and destination do change.
Its all about controling and using the additional dimensions of a fluid medium. While the nature of fluid conduction is understood controling it through switching without reversing polarity is new and unique.
