the bullet leaves the barrel at a said trajectory. The point of having the cross hair level to the receiver causes the bullet to be leaving the barrel in line with the vertical crosshairs.
If the crosshairs are off set then the bullet would appear to be leaving at a diagonal direction when referenced to the vertical crosshair. making it next to impossible to adjust the scope as it operates on a vert/horz axis. and this is only amplified as the bullet reaches further out
Think of it like a Etchisketch...easy to go up/down or sideways. But it takes a real hand to adjust it diagonally.
That may not make sense, but I cant describe it better
