Is this... Is this normal moderator behavior?

I shared a link to what I have found to be an incredibly amazing interaction between a "Specialist" (Not sure the difference between a Specialist and a Moderator) as he/she attempts to discuss the meaning of "racist" language with other's on the boards page. I have never seen a moderator behave like this before. I don't think it's bad or anything, and I definitely think the "Specialist" is doing his/her best, but this just doesn't seem like the behavior a moderator should demonstrate XD
