If you are just going through the “What’s New” collection then sure, those little segues aren’t going to match the list in the sidebar. If you hit ⌥⌘R to Reveal the “Metadata” section in the binder, you’ll see “Snapshots” is right there where indicated.
A collection is of course a sampling of the binder, a list of files collected from it. The text inside of those items is unaware of that listing—and is well, just text, not a dynamic piece of user interface that can be changed depending on the context.
