The rules state that the horn ends the period, unless a try is in flight. So when there is no try to handle, what would a whistle after the horn signify? Consult your Shakespeare here.

It might signify that the horn was valid because at any other time when the ball sounds during play, we tell the players to ignore it and play on.
