Alan,
I believe that most of us agree with your point, but when you don't 
have adequate test equipment or perhaps the expertise to utilize it, 
on the air results indicate success or failure.  My Carolina Windem 
and G5RV antennaes are separated by perhaps forty-five feet and run 
in essentially the same directions, but when I installed the second 
wire there appeared to be no degradation in the way that the first 
antenna performed and the added antenna seems to work well also.  And 
both wires allow me successful contacts as often as not, so 
unscientifically, I declare both antennaes a success.
thanks.
