Actually I suspect that this "feature" is a throw back to the old Server Side Imagemaps where the x and y are the co-ordinates that, possible refer to something useful on the image ( a country, a face etc..) Of course it is now more efficient to use a client side image map, but I could envisage that a server side imagemap could still be useful, though not in connection with a search button, unless you were incorporating an Easter Egg into your application.
