A friend comments:

start from figure 2, turn the half mirror at D round so it faces the other way, now E will light up instead of F. Since his explanation doesn't allow for that we've just proved his explanation is wrong.

Anyone know if that's right? EDIT: seems clear to me both detectors must light up if you do this. EDIT2: it turns out that by "turn around" he means through 180 degrees, which should surely mean no change.

It turns out he was referring to this error; see How accurate is the quantum physics sequence?
