Square waves have cascading, odd numbered harmonics.
The ringing one would merely be out of step with the others.
Nothing to do with the frequency of the wave or its harmonics. Each
ringing event is separate and is triggered by the broadband energy of
the rising or falling edge. The frequency of the ring is determined by
the LC circuit that is being struck by that edge. The ringing will be
restarted at twice the frequency of the square wave, but that is not
the same thing as the ringing frequency.
