If you evaluate the modes at an energy at which both bands are open, then yes. You will need to refer to the documentation to find out what order the modes are stored in. > And the orbitals in this case, corresponds to spin?

If you haven't implemented spin or anything then there will not be any spin. I would expect the `wave_functions` array to have shape (2, 4) in the case you described above, i.e. there are 4 (2 left-going, 2 right-going) modes and the wavefunctions have 2 elements, corresponding to the 2 sites in your unit cell.
