You need iCloud Drive to sync the books, so the ID used for iCloud must be the same as the one used for Books. From the article you linked from.
Turn on iCloud Drive to sync PDFs, EPUBS, and books created with iBooks Author that you didn't purchase from the Book Store that you added to your Library across all of your devices.
On a Mac, first turn on iCloud Drive: Go to Apple () menu > System Preferences. Click iCloud and select iCloud drive. Then, open the Books app and choose Books > Preferences from the menu at the top of your computer screen. Select "Sync collections, bookmarks, and highlights across devices" to sync your content with your other devices.
