    I’m not sure what the ‘equation on the previous slide’ is referring to. My guess would be the Hamiltonian, which has terms related to Iz, I+ and I-. All of those operators respect the azimuthal rotation symmetry of the system.

    Visually, we can see that rotation around the z-axis does not affect the energy. So since we chose the xyz-axes, the symmetry corresponds to rotation in the xy-plane, which is reflected in the axis system.

    From other answers, I gather that the symmetry is relfected in the fact that Vxx=Vyy, which is a better answer to the first way to see it.
