No, that's single-phase. The "phase" is measured across the hot wires; the wire itself isn't the phase. There's no such thing as "two-phase".

Yeah, I got confused because some people lazily refer to split phase as "two phase". Apparently I need a refresher session with my textbooks. :(

Actually there is janky 90 degrees out of phase two phase power. Who knows if there's anywhere still using it but it was a thing.
