I was hoping that they were proxy/wrapper Linked Data URIs i.e., they 
resolve to description documents [1][2].

I've also looked at:
1. 
http://www.imagesnippets.com/imgtag/images/mm@carmapro.com/P1010996.html 
-- which uses an RDFa data island to expose the RDF metadata
2. http://www.imagesnippets.com/imgtag/images/mm@carmapro.com/P1010996 
-- this doesn't resolve, but it is a candidate URI for a Linked Data 
proxy/wrapper URI.

Yes, that part is clear,

Yes. Basically, reflecting the duality of Linked Data URIs whereby a 
single URI enables entity denotation and discovery of documents that 
describe said URI's referent.

DBpedia.
