Illustrative logo is about mascots only?

I don't think it was stated explicitly in the video, but I believe it implied a logo is a symbol, like the simple and somewhat meaningful Nike swoosh, while an illustrative logo involves drawing beyond basic shapes. I couldn't find an example of a strictly illustrative logo; many vivid logos have an illustrative logo or a mark logo, with type attached but slightly separate. See the KFC logo when it includes Colonel Sanders, or the Jaguar car logo when it's just the leaping jaguar. The illustrative parts in those two logos are moderately detailed, compared to something like the deer used in the John Deere tractor logo which I believe would qualify as a mark not an illustrative logo. One point I find interesting about logos is that most people could successfully draw the Nike swoosh, or even the John Deere logo, but not everyone could draw the full KFC logo without a reference image of the guy.
