We have no disagreement on the physics, just the terminology. You can
certainly use "180 degrees out of phase" or "different phases" if you
want. IMHO it is excessively complicated, not useful, and can lead to
confusion, miscommunication, and error (as by David).


Actually, I have no objection to saying the "A-leg" is 180 degrees out
of phase with the "B-leg" either (though I would state it differently).

I have a problem with making them different "phases".
