What happens when you lower your arm you actually move the string away from your nose, then to get the string back on your nose you slightly tilt your head forwardwhich will bring everything back into alignment right?

No it's wrong because now that you have done that your release hand is not at it's normal anchor it will be slightlylower and a tad furtherbackon your face.

Thus making the shot go hot on the target even tho the peep and pins are lined up.
