Can the same model convert A to B and B to A?
The training seems to be symmetrical A and B, so I wonder if there is a way to use the same model to faceswap both ways?

Yes click the "Swap Model" checkbox in the settings or use the "-s" command line option.
While the guide mentions this is useful if you've gotten A & B confused, you can do it intentionally if you wish, changing the setting based on the video you are swapping into.
Swap Model - When people start out, they often train the model the wrong way around (i.e. have the A and B folders wrong when training). If you find your swap just has a lower quality version of the original face on it, then you have trained the wrong way around. Enable this option and remember to train the right way around next time.
