That doesn't sound much like what I think of as neutral - ie, something
that has zero nominal voltage to ground.

Certainly if you have three phases 120? apart such that there is
240VRMS between any two phases, you can center-tap between any of two
them, but the tap won't be 0V to ground and thus I would maintain that
calling it "neutral" is misleading, enough so that I'd call it
_dangerously_ misleading. (By my calculations, it will be something
like 70V to ground, but I'm not sure I have the math straight.)
