It steps it up to 240V then center taps that coil for split phase 120/240V output.

Interesting.. ok so basically wired that way, I can have 240v or 120v shore input power and single phase 120v back to house? (I really only need single phase.. but have a 120V generator and 240V shore power at the moment)

Unfortunately, I didn't completely understand your question.

If you had the two sources isolated and connected them individually, I believe you would get what you want.
