Given that he was talking about a change which occurred as part of a major product launch which has happened since the FAQ was published I think it is shoddy journalism. I don't think it takes a genius to work out that when a new product is launch old documentation might not apply to it. Moreover he knows for a fact that it's no longer accurate - he's discussing a new file format (.ibook) the existence of which provably falsifies the statement in the FAQ. In terms of changing updating the FAQ yes it would be good but as far as I can tell for Apple and most others common practice is to leave the old version and add a new version rather than change them. It can make finding the right information difficult and certainly product versions on them as well as the date would be useful but I don't think you can read much into the fact that no-one bothers to manage their information on-line particularly well.
