It's a difference between making mv/move, cp/copy client-server aware and making the shell running these simple utilities client-server aware.

The Windows way would be to mount the remote filesystem and use local mv and cp. Which works fine, since Windows has excellent remote filesystem support. The Unix world only partially began to catch up to CIFS with the advent of NFSv4 and its lease infrastructure and it still isn't as seamless as the Windows stuff.
