.380/9mm

Just curious.
The 9mm and .380 both use a .355 bullet, the cases are the same diameter, and the rims are the same size.
Why do they require different reloading dies?
Logic suggests that they'd be more like .38/.357 or .45/.454, needing only an adjustment to the seating die.
Where is my logic falling apart?

(Yes, I know they were birthed separately but the end result would seem to matter more then parentage)
