mainly it's an aspect ratio that they try to keep.
usually when you do split screen, it shows less above and less below. the sides are normally the same.
when you take a widescreen game and split it on a wide screen, you will not be able to keep the aspect ratio and use the full screen. playing on 480 resolution tv would more than likely use the full screen because it's basically a 4:3 vs 16:9 or whatever the format may be
what they should've done was make the map or equip menu appear in the blank space thus keeping the widescreen res and also not waste space.
