Topband: Phased Vertical Question

I am attempting to put up and make work a couple of phased verticals before this weekend.  Couldn't find my ON4UN book and asked a friend on the phone to read something that I remembered that concerned me. It says something like "to preserve symetry have the lines to the verticals connected at the center of the array, and even gives an example in the case of an end fire array spaced 1/2 wavelength not to use 90 and 270 degree lines but 3/4 and 5/4 wavelength lines instead. 

I was going to bring the 700 feet of hardline (3/4 wavelengths to each vertical to the house instead and never dreamed that could cause a problem.   Can someone explain approximately what the real world difference is between having 700 feet of hardline on the ground between two verticals spaced 193 degrees apart with the relays in the center of the array versus having it all coming to the shack which is not in the center of the array?

Thanks...Stan, K5GO
