You're correct. I struggled to find it before, thanks for pointing me in
the right direction.

For reference, here's the relevant snippet:

$ nix-env -qas '*' (show status of available derivations)
-P- firefox-1.0.7   (not installed but present)
--S GConf-2.4.0.1   (not present, but there is a substitute for fast
installation)
--S MPlayer-1.0pre3 (i.e., this is not the installed MPlayer, even
though the version is the same!)
IP- ORBit2-2.8.3    (installed and by definition present)
