I think that the extra element is connected correctly on the foreword driven element... screwed to the center of the bend. I would guess that the rear DE has holes for similar attachment of the extra element.

IIRC, some marketing people dubbed this a "NEW, IMPROVED TRIPOLE DESIGN" ... Supposedly improved the impedance matching of the two DEs to 300 ohm line.
