It can happen to anyone, and there's a certain point once they're bucking past which it's too late to redirect that energy. At that point to take ahold of him will actually help to engage him further which will have the effect of him bucking even stronger! Once you cross that threshold your best bet is to do your best to ride him and think forward
as your way out the other side.
The alternative is to ride more actively and start earlier, rather than waiting until things have fallen apart and then trying to make an emergency recovery.
This is a good example of trying to make an emergency recovery too late. If you watch closely you can see that as soon as I took ahold of the lead rope he really engages and starts getting even more elevation! Which ultimately led to coming out the back (lucky I didn't get kicked, too)
Here's the next ride I did on that same horse where the idea was to start early and ride more actively. In particular, working on bending the neck and un-tracking the hindquarters similar to your one-rein stop
As you can see by being much more active and busy I was able to get him rode that day. The main thing I saw to improve on that ride after watching the tape was to slow down what I was doing, and start building him up more gradually with proper movement as in this later ride
Even watching that last one now, I think I could be even getting more done with less. It can really help to start thinking about small incremental improvement when you're trying to build back lost confidence between yourself and a horse. But the upside to that is, once you get onto that it'll make you better. Really gets to be a lot of fun too.
