Unless there was, at some point, 3 phase brought into the home, each phase from the transformer was derived from a single phase on the pole.
It's quite common for businesses and industrial buildings to lose a phase as they have true multiple phases entering the building. Residential phases are all split from a single at the transformer. Again, unless there was 3 phase in the building for some reason. Those are truly separate phases.
