It says "Web definition" then shows the exact definition from the deleted glossary page followed by a link to it.
The knowledge base Metaweb built is called Freebase, and it’s still in operation today. It’s a collaborative database—technically, a semantic graph—that grows through the contributions of volunteers, who carefully specify the properties of each new entity and how it fits into existing knowledge categories.
While Freebase is now hosted by Google, it’s still open to submissions from anyone, and the information in it can be freely reused under a Creative Commons license. In fact, Microsoft uses Freebase to give its Bing search engine an understanding of entities, which is the same role now played by the Knowledge Graph at Google.
In a semantic graph, there are no rows and columns, only “nodes” and “edges,” that is, entities and relationships between them. Because it’s impossible to specify in advance what set of properties and relationships you might want to assign to a real-world entity (what’s known in database lingo as the “schema”), graph databases are far better than relational databases for representing practical knowledge.

Anyway, the point is, nothing 'goes in a straight line' with the Knowledge Graph (build on top of/from the Freebase DB) as far as I can tell ... The whole thing is about relationship mapping ... The easiest way I can think of to 'put it into an understandable picture' easily, is to say, 'Think along the lines of 6 degrees of separation, only with people, places, things, events, queries, etc. and how they relate to each other.' ... Pulling something out of the middle of that isn't likely to be as easy as it seems, in fact I would also guess to get something 'out' it probably has to be replaced by something 'essentially the same' to not cause issues once it's in there.
I do definitely think it's along the lines of what you're saying about something 'staying' after it's deleted ... I just thought I'd people give some more background on it since it's relatively new.
I remember a site that was shut down (run by somebody else) gradually drifted down the SERPS for several months before vanishing.
