I don't think it's that obvious.  There are two possible scenarios:
(1) After hearing East's explanation, West realizes he screwed up and
forgot the system.  (2) After hearing East's explanation, West
believed that East forgot the system.  The auction should continue the
same way either way, since (by the UI laws) West needs to bid as if
East had explained 2D according to what West thought it was when he
made the bid (it's a bit more complex than that, of course, because of
logical alternatives).  But in case #1, nobody would have told North
anything, because there was no misunderstanding or misexplanation to
tell North about (and there is no requirement to tell the opponents
that you misbid); while in case #2, West would have believed he was
required to tell North about East's supposed misexplanation.  So I
don't understand how Bramley would have thought the answer would be so
obvious.
