No truth at all.

The physical result is three parallel wires but electrically connected so as to form and "up, down and up again" element.   This supposedly raises the radiating element impedance relative to the fixed ground loss resistance.  The idea I'm told, is that since the ground resistance (loss) is fixed at whatever it is but as the actual radiating element impedance is raised, the antenna becomes more efficient since the ground loss percentage of the overall feed point impedance is lowered.  This impedance change happens in much the same way as a folded dipole feed is a higher impedance than a conventional dipole using a single wires.
