As an electrical engineer whose major was "power" (back when it was
actually taught) I would agree wholeheartedly.  The "2 hot plus neutral"
is most often a single phase of a three-phase delta 240V secondary with
tapped center as "neutral".  It could not be two phases of a wye because
the voltage from phase to phase would then be 208V for 120V
phase-to-neutral.
