This would only be true if the 3 phase is Wye connected. A delta
connection has no "neutral" and wouldn't do this.

Right?

Well, sometimes. Center tapped delta is very common in some parts of
the US. This is the service with the 'wild', 'high', or '*******' leg
that gives nominal 208 volts to neutral, while the other two give the
expected 120 volts. Usually the mill will be supplied by only the 3
phases and no neutral so there is no 120 or 208 there (not counting
doing something dumb like using ground as neutral). Sometimes there
might be a 120 vac circuit adjacent to the 3 phase disconnect for cord
and plug connection. I just use a separate SO cord over to the nearest
120 volt outlet for power feeds, coolant pumps, DRO's, work lights, etc.
