Exactly and that why it's a powerful metaphor of how software development works, especially when explaining iterative programming. I'll always take a stand when I see it to justify bad practices, bugs and sloppy coding. Elsewhere in the video also explains why it's not about low quality code: because you need to have a good design and codebase for it to be refactorable, to maintain your development speed as your understanding of the domain/technology grows.
