I don't know - I've seen a horse topple over when the rider did that particular stop, galloping at top speeds. After seeing that, I have never liked the 1 approach.
I used to ride a TB Gelding named Dodger - he loved to play games while out and about. Fox Hunting, Hacking, CC course. He would love to take off in a bolt, with some crow hopping. He did it once in a blue moon, but when he did it, it was enough to make your heart leap into your throat.
When I did the Eventers 1 rein stop, it put him to a halt, and a halt very quickly.
I've had Nelson bolt on me out on Fox Hunts, when - at, who knows what decides to make him spook and panic. The Eventers One Rein Stop makes him put on the brakes likity split.
