Germany allows a 2-3 line breeding. Which if the litter's sire and dam are 1, grandparents are 2, and great grandparents are 3. So the closest line breeding approved in Germany would be The sire of the sire, being the grandsire of the dam.
This is often done because there are traits that that dog has that the breeder wants to come out strongly/correctly in the puppies. It can set type. And it is your best chance at having a uniform litter with the characterisitics that you want in your line.
In AKC, there are no such rules. In fact, I think it was in The German Shepherd Today
by Winifred Strickland and Jimmy Moses, that says the best way to get a champion out of a champion is to breed father to daughter, mother to son. I am not sure of the exact wording. This may also be done to see what recessive genes are present. Because, while close in-breeding does not create problems, the limited set of genes means that what is there will come out. In that book it also said that one needs to be able to cull the litter -- and reading the whole book, the author was not talking about altering and putting in a pet home, they mean putting puppies that have even minor issues down. But I digress.
You need to know what you are doing to breed closely. Now people talk about the Coeffiecient of Inbreeding and Back-massing. How many times is that double world sieger in the seventh or eight generation, and what will that mean for these puppies.
The point in this thread is that there is no way to know whether you are breeding father to daughter, much less how many times a dog that is known to produce hemophilia is in the seventh generation. And don't believe that dogs will be unlikely to be related, where one dog is without papers, finds an owner willing to breed to their papered or non-papered dog, it is very likely that they are from the same breeder, or bred to the same dog and close in relation.
