A tangent, but a true "appeal to authority" would be using the fact that someone is an expert on a subject as the evidence for the assertions. I don't think merely mentioning that you or your source is an expert of a subject is necessarily an appeal to authority falacy. In this case they provide their opinion and then provide the reasons and evidence for their reasoning.
