This is equivalent to:

$ nix-channel --update nixos
$ nixos-rebuild ...

So it's just a convenience.

This is obsolete, but it may be useful for people who don't use the channel.  It
gets the latest NixOS manifest, but there is no guarantee that the manifest
corresponds to your NixOS/Nixpkgs revision.
