Nope. And that's not "theory," that's someone's dumb idea. :)

BUT -- using multiple spaced conductors in parallel and connecting them 
at both ends makes the conductor "thicker," which both lengthens it 1-2 
percent and broadens the SWR bandwidth. The same thing happens with a 
tower as compared to a single wire. The vertical part of my 160M Tee 
vertical is a pair of #12 spaced about 9 inches. When I added the second 
wire, I observed that my SWR bandwidth approximately doubled.
