It's definitely a bug in the book. In tile-display mode, I am pretty certain that there's no way currently in the implementation to get non-LOD data to the client. However, that being said, I don't object to adding a new setting option or maybe using the existing "checkbox" to enable fetching non-LOD data to the client.
