I think what was meant (at least how I read it) was the civilians were irrelavent to the story

Sarek was pulled out of retirement, most likely he was representing only the Vulcan Ggovernment, and had no connect at the time to the federation.
At various times in his quite long career he could have been at different times, the Vulcan ambassador to the federation, the federation ambassador to a federation member, the Vulcan ambassador to a species or government outside the federation, and the federation ambassador to an outside species or government.
