Listing Expiration Settings

The options are not clear on this page “Listing Expiration Settings” and the question mark help icons are not elaborate at all. For example, what is the difference between expired, closed down, pending review, draft, etc… those all seem like they would simply be hidden, are they accessible in different ways yet hidden in different ways? Are these effected by the expiry check box above it, etc…

Could you make the question mark be a more elaborate explanation? Could you make a hyperlink on this page (and other pages) that goes to a help page where the options are explained in detail? Maybe a video that goes over how these plugins interact with each other?
