I think that's a deliberately uncharitable interpretation. If you're admitting there are problems in the previous redesign (and you are), then why not fix those pieces rather than redesigning the colors, icons, and entire rest of the interface? It's not so different from an engineer who rewrites a whole service because it has 3 bugs. Almost never worth.
