My understanding is, and I could be wrong, that "two-phase" in reference 
to modern mains circuits does not exist. Circuits with two hot legs, L1 
and L2, are single phase and referenced to each other. Two phase used to 
be two legs that were 90 degrees apart, but is long gone.

I had fits trying to understand how rotary three-phase converters worked 
until I purged the notion of the input being two-phase.

Two phase does exist for stepper motors.
