That is true of 115-volt coming off the same power leg; not true of
230-volt without a proper load between those two conductors = BANG, a
direct short!
Of course, Doug knows that.

For purposes of that rule (No current can flow between two points that
are at the same voltage [& phase])

Please don't edit my quotes. If you have anything to say, please be
honest and say it yourself.

the 2 legs of 230V are NOT the same [phase] voltage.
They are opposite [phase] (180 degrees out of phase).

Notice that here I already said "phase".

That's like +10 and -10
aren't the same number.


Excellent description, the opposite legs [phase] of power are
180-degrees out of phase -
Therefore, due to being 180-degrees out of phase, the same 115-volts
potential each possesses is doubled to 230-volts.
However, either leg will deliver 115-volts across a load to neutral or
ground.
I am sure Doug knew that.
