Isn't it commonly called Split Phase in North America? Draw 15A on each side of the 120-0-120 VAC circuit and measure that with a clamp on ammeter and you get 15A on each leg. Put the clamp on meter on the white wire (the neutral return) and you get 0A. In effect the two phases are 180 degrees out of phase. If it weren't so you'd have to make the white neutral wire handle twice the current of the black (and/or red) hot wires.
