I'd like to understand the reason behind limiting the shutter speed like this?

Because the shutter blades and the aperture blades are the same mechanism.  They can obviously close from a small aperture faster than from a large.   The alternative would be to limit the top speed to the wide open speed.   This is not uncommon on fixed lens digital cameras (e.g. Ricoh GR).
