Out of curiosity I rebuilt maiki’s post above to see if it would now show the correct onebox info for each, and it does indeed. 
It’s now a much better example of both inline and regular oneboxes.
An inline onebox is one where a link within a block of text is automatically converted into a nice readable title (the first one). Whereas a regular onebox must be a link on a line all by itself, which generates the special box with all the extra info and image in (the second one).
