Almost everyone uses them like that. It's the index of the right point in the graphics buffer when treating it as a 2D array.

Back when image maps were common on websites, it was also easy to find the coordinates in your image by placing your Paint Shop Pro crosshairs at the desired points in your image and then transposing those coordinates to the html. Using a relative number for the second point would have added a lot of work for complex image maps. Maybe that's just a coincidence because it was actually driven by the underlying array, but it was super helpful on the design side too.

PS - This brings back my memory of server side image maps which were fun for treasure hunt type images because you couldn't view the page source to figure out where the hotspots in the image were. Good times.
