I take it to mean that the code quality deserves more scrutiny because you can't guarantee what it has provided is quality code, without reviewing it first. The same applies to brand new devs — it's normal to apply a little more scrutiny because they simply don't have the experience to make the right decisions as confidently (or frequently) as someone more senior. It's an analogy and the natural fact that output reflects experience and practice over time.
