You are correct. No rotor that is below minimum thickness is safe on any car for risk for hyper-extension of the caliper pistons.

As a matter of California state law, no parts company will turn a rotor that results in an undersized thickness.

Correct once again, since the resulting thickness after turning met the minimum thickness spec, it was permissible.

The results I experienced are excellent so far.
