That shows the parallels and differences between tonight's game and the Kentucky game. I've not rewatched it, but given what you have said, contact in both situations was initiated by the referee. Contact was returned by both Richt and Snell. In Richt's case, he grabbed the referee by the arm while Snell didn't do anything like that. Both were flagged. Both, by rule, should have been ejected. Snell was ejected for essentially refusing to be helped up by the referee. Richt was not ejected after forcibly grabbing a referee by the arm. Same rule, two different results. IMO, Snell was treated unfairly while Richt was given preferential treatment.
