Some games do, some games don’t. It’s a design choice.

Also, Oblivion was released originally in 2007, and Morrowing in 2002. The consoles, game logic, and gfx were a fraction of what modern games can do, a lot of games back then didn’t have the fancy animations for all directions. Either because no one bothered to put in the time to do it, or there were other backend/engine limitations at the time.
