Shotgun offense - Offensive line

As one who runs the shotgun a lot, I like the two point stance for two reasons:
1- being in an up position, your linemen can see and recognize stunts and blitzes.
2-You are not fooling anybody about what you intend to do. There are good teams who do run the ball out of the shotgun, but it is still the pass threat is the reason you run the shotgun and even most of your run plays come off a draw action.

Coach C is absolutely right, though, the technique is much the same whether down or up, it is more just a matter of preference. But, for me, the vision thing noted above was the main reason I like it.
