Indeed, Anderson showed somewhere else. But where? There was only one path to the control panel, and that's the same path that Shepard took. Shepard even passes by the chasm that Anderson mentioned. Shepard gets to the control panel shortly afterwards Anderson does. Knowing that, there's no way Shepard wouldn't have at least seen Anderson on his way to the control panel.
