After thinking about this, I've come to the conclusion that it doesn't.
"Phase" implies a relative-timing relationship. Simply inverting polarity
doesn't change the timing between the two waveforms.

If you compare the timing of the positive part of the sine wave you will
see that the two signals have different timing.

No more than your image in a mirror is a separate being.
