I suppose it has the advantage of looking intentional, not that he just "forgot" to remove the fd. I think a neater one could be made from a fd braze-on adapter clamp with a retaining bracket bolted on in place of the fd. It would be a lower cost, home made version of the Paul chain keeper Kimmo referenced.
