Peer at those books closely and you can see some odd detours that were shut down. Also some padding to get more segment-by-segment payments. But it's workable

It's interesting to consider the meta-version of serialization..novel sets. Nothing new here, the Oz books being an obvious example, but it's funny how it plays into a human need to both read about familiar characters or places and to have physical sets of books that match.
But even for larger book series this happens. Like Wheel of Time, one can in an earlier book read about Lan sitting and sharpening his sword. Some books later it's mentioned that his sword never loses its edge. So in later versions of the first book it has been changed to him sharpening his knife instead.
But my guess is those things would happen on a larger scale when not having the opportunity to go back and edit previous chapters.
- write it at once and release in chunks.
- release it as you write.
- And the most interesting (in my opinion), release it as you write and then if it’s popular, do a full round of edits based on crowd feedback and self publish the ‘definitive, crowd edited edition’.
It can produce some strange incentives: For one thing, they start getting reader feedback after every single chapter, if they want it. Some writers develop really fast-paced styles.
For another, they often start releasing chapters as they are written - meaning they can't have an editor who reads chapter 20 advise them to go fix an inconsistency back in chapter 4.
Also, some writers realise the moment they bring the story to a conclusion, they stop getting paid. That's OK for comedy/slice-of-life/X-of-the-week content - The Simpsons has no need for character growth or overarching plot lines - but works poorly for other genres: What good is a romance where the characters can never kiss, or an epic fantasy where the one ring can never be thrown into mount doom?
Of course, some of these incentives are hardly new: Other media have been subject to them for years.
