Really?
I've always done the opposite. Although there's a whole lot of experimentation involved.
The pickups on my L6S raise and lower by almost 1/2" and I've always found that in order to get the best sound I have to raise the bridge pickup as high as possible under the 1st, 2nd and 3rd strings and lower it under the 4th, 5th and 6th strings.
That way I get more volume out of the higher strings than the lower ones ( I generally use the neck pickup for softer stuff without distortion).

On the bridge pickup, it's pretty much even under all 6 strings, but again it's as high as I can get it. (The bridge pickup is usually used for 'chunking, overdrive and leads... although for tapping I usually use the neck pickup.)
