The Nut is offset on the G string side,No I'm not wearing my underwear backwards!

I was going to ask my question in a slightly different way.Maybe I should have.
Anyway, the distance from the edge of the G string to the edge of the fretboard at the nut is 1/4 ". on the B string side it's 6/32 " from the edge of the B string.Now I realize that the B string is thicker and the measurement should be from the center.I have a 125 B and a 45 G string on the bass.Probably nothing to worry about but I have just about tinkered with everything else on this bass so why stop now?
