Uninstalling a program via the Add or Remove Programs GUI doesn't clean up the registry entries. I noticed this awhile ago and realized I had hundreds of old registry entries for games I had uninstalled a long time ago. Plus, most people using Steam uninstall games through Steam. So if Steam isn't cleaning up the registry that entry will stay there. I don't think the registry entry will do anything, but it can't hurt to remove it manually.
