It depends on how you measure. In terms of RMS or power supplied, they are in phase, but when graphed on the same axis they appear to be shifted by π radians. But historically "two-phase" meant a shift of π/2, and this is not that.

with multiple phases you can generate additional phases with linear combinations of the phases
