Why does this Tracey Ullman-era animation of Homer look way better than in early-season episodes of the actual show?

The animation was super rough throughout the run of shorts on the Tracey Ullman show, but this one about Bart taking a bath randomly had surprisingly sharp artwork for Homer compared to the other shorts, and even compared to the early seasons of The Simpsons. Am I wrong in thinking this looked even better than his character model on the show until at least midway through season two or even season three?
