This is key. It's also different from his earlier "keep them pretty."
Accurate, on-model, expressions of emotions like anger or disgust are NOT going to be pretty. These emotions distort the face in ways that are mutually exclusive with pretty. In particular, with disgust, you cannot have "pretty" and "on-model" without wandering into "uncanny." The solution is to surrender "pretty" just as one might have to with a live actress. "Uncanny" is as bad as it can get in animation.
It should be noted, that it is possible to achieve uncanny even with a live actress these day, through the wonders of BoTox. That too looks bad on film.
