Since the lawsuit was successful, the order given was proven to not be lawful. Thus, not insubordination.

True, but it's still the case that he was fired by his company with the claimed reason of insubordination. I think it's a valid translation given the context (i.e. talking about what they said he did, not about what he actually did.)

Sure, but that wasn't the expectation of the company at the time they called it that.

If the court ruled in their favour it would have been insubordination.
