I almost never post on this forum. So please forgive me my detail and commitment to what I describe below.
A dead release (draw hand) or leaving the bow arm "up" until the arrow hits the target are like stopping the baseball bat when the ball is struck or the tennis racket when the ball is hit.
The only way you can perform those unnatural movements is to allow your body to prepare for the "stop" before contact (release) is made. to keep the bow arm "up" until the arrow hits the target promotes collapsing (inward folding of the bow arm shoulder). The dead release is just a smidgeon away (if you are lucky) from creeping.
The bow arm and drawing side back muscles must remain active throughout the shot. This results in a highly animated follow through, one that prevents you from messing up your shot.
When done correctly, the draw hand will slide along the face, under the ear (if anchored at the mouth) and the thumb will end up on or near the shoulder. The bow arm will jump towards the target and fall to the side and drop. The arrow is long gone before this animated follow through begins.
To execute such a shot you must "set up the shot" by keeping both sides active and initiate a slight movement of the draw side scapula. When that scapula budges, relax the back of the draw hand and fingers at once. The reaction will be instantaneous and involuntary follow through.
I've trained more than 7,000 adult archer instructors in the past 16 years, 8-48 hours of instruction for each. I am not a coach. I've found that bow arm follow-through is much more difficult for most people that the drawing side.
Doesn't matter what type of vertical bow the archer is using, the form, execution, and follow through are the same.
