What does all the sync options (on windows )mean?

What does the options in tools-settings-sync mean on windows desktop version?I didn't find any doc/articles on this. I'd like to try these because occasionaly it seems syncing have conflicts with my input method.

You can hover over each with your mouse to get a tooltip for each.

The one I am less sure of is "Joined Notebooks" (and the over help says "Joined Notebooks").  I suspect this is if someone else has shared a notebook with you --https://blog.evernote.com/blog/2012/12/07/quick-tip-friday-notebook-sharing-with-evernote-for-mac-and-windows-desktop/ It makes sense that you could synch these at a different schedule.
