This must be because you have a system, that allows you to map unused lower memory addresses as useable conventional memory, so that total base memory is something like 704K. This is kind of cheating since many people can't do this. (VGA, don't have the chipsets that allow it, etc) These people want to get as much as they can out of 640K base memory which is all most people have in their machines.
