Yep, that is how 415VAC is obtained.
But is it how it's metered?

I haven't gone through the math, and I'd overlooked the fact that
each meter sees a power factor of less than one, so I can't say now
whether I think the meters would read correctly. But if there's a way
of looking at the problem that makes the answer obvious, I've yet to
see it.

Do it the old fashioned way: make a test! Can't be that difficult, can
it?

Of course not. I'll just get out the 415VAC resistive load I happen to
have lying around, and see what registers.

Two large lamps in series.


I don't have any. I'd have to buy them.

Anyway, all a test would do is show that the answer is probably correct.
It wouldn't make it any more obvious.
