It's more of a visualization tool than anything else - it's hard to work out how exactly a Beyblade's profile deviates from a perfect circle.
Functionally, this is a lot like a Mercator map projection - there's minimal distortion towards the edge of the Beyblade (the equator on the map), but as you approach the center of rotation (the poles on the map) the image is increasingly distorted. In the case of Beyblade, it's important to remember that the stuff on the edge is what's moving fastest, and is therefore much more important than slower-moving features closer to the center.
EDIT: I suppose it's more like an equirectangular projection, but I doubt anyone cares enough about maps to gripe about it.
