Agreed. It's just as feasible that the beneficial effect is derived from his sense of taking control over his condition rather than being controlled by it (effectively feeling like an active rather than passive participant in his depression). I make no claim that this is actually the reason, only to provide one feasible, untested alternative theory. Further scientific study in this field should be very interesting indeed.
