Because software changes so rapidly. I imagine you’re right in practice, but one might also ask whether code that is changing faster than understanding is changing too fast. It’s not as if mechanically updating literate-style documentation to reflect a change should be disproportionately expensive compared to making the change itself, or to making corresponding changes to test suites, getting the code reviewed by other people, or getting the changes merged into source control.
