I don't think they are counted as "actual links" but they may count as a "reference". Many researchers will utilize this type of addressing for their audience so that they can print documents and have the link references handy. I see it day in and day out.
In the reference you provided, I'd be suspicious about that one. I have a feeling that the "reference" was once an "actual link" and then turned to a "reference" after it served its purpose. < Me "Tin Hat" is on.
What surrounds the http reference? What is being "associated" with the http reference?
Also, searching for these types of unlinked "references" will turn up some pretty interesting stuff. You can find a good deal of the scraper activity through these types of searches.
