"My example refutes your claim that authority never makes a truth to be true"

No it doesn't. The authority simply made an arbitrary decision amongst two equally valid decisions. Neither decision involved a judgment of true/false whatsoever. It was impossible for the decision to be false and the corollary applies. The question involved the arbitrary choice of left/right. Completely arbitrary choices are irrelevant.
