You don't need to set up that alias. I'm guessing it's a holdover from the DOS days with Norton commander where you would launch nc just to quickly navigate to a directory and then quit it, which can't easily be done on Unix. (the current drive/directory was global state in DOS - it even recorded the current directory per drive, but that may only have been command.com doing that)
