The ESP Guitar Company

So I've got a 2007 LTD WA 600. Looking at the archives in the 2007 catalog it indicates that the guitar is set neck construction, however I can see lines on the back of the body from the nick to the end of the body that make it appear as though it is a neck-through construction. Can anyone tell me if the specs have ever been off in the catalog or what I might bee looking at if not. Looks exactly like the KH neck-through. Any help would be greatly appreciated.
