Agreed. It's rule-set is indeed complicated.
I discovered another "rule": when removing all books from the top-line, save for the one I'm currently reading, then "magically" a collection to the right appears based on the author of the book I'm reading. It even indicates the amount of unread books for that author.
It is a nice-to-have feature, but totally uncontrollable and disappears when you open a second book.
