Exactly, the proper response should be "Then why the fuck didn't you write that down when you wrote the code?" People not documenting the code's intention bring down the whole project. Sure, sometimes the code _may be_ right, but without documentation, you can never be sure... It inevitably results in a trust-no-one environment where you can't change a single line safely because it might be doing something else: the weird side effect might be used in some other module, or it's sanitizing data from library X that's no longer used, but nothing is documented anywhere, so you never know.
