It really is that simple. If you
make N=90, you have the old 90 deg two phase implemented over 3 wires
instead of two.

And what if you make N = 180 deg

How many phases do you have now?

Two phases, which is precisely my point. If you have two phases at 90,
two phases at 179, two at 181, then you have two at 180.
It's all consistent. Otherwise there is a "parlor trick" at 180.
