Ahh, the penny drops! The driver treats "Read" as a virtual collection. When you finish a book on the device, it is marked as "Read". When the driver is collecting the list of books, it puts all the read books into this collection and shows them in the device list. Then, when updating the books on the device, the driver is treating books in this collection differently. It doesn't add an actual collection because at that time, it doesn't know if the user put the book in the collection, or it is there because it has been read. In calibre, my #status column has "Finished" for books that I have finished reading. I was looking at this recently and trying to work out why this wasn't consistent with my "Unread" and "Reading" statuses. This explains why.

There are some other virtual collections used by the driver:
  • "Im_Reading" for books marked as being read.
  • "Overdrive" for books borrowed from the library and downloaded from Kobo.
  • "Preview" and "Recommendation" for previews recommendations from Kobo. But, these are only seen if the appropriate driver options are turned on.
  • "Shortlist" is from older firmware. At that time, there were no collections and this was a way to group a few books together.

Plus some others that I don't think happen in recent firmware.
