You are wrong in thinking this. Horses and ponies will just freeze in their tracks to get out of work and has nothing to do with balance or contact either. Will also spook, bite, back up, rear, throw a fit.
Has to do with them having mind of their own, figuring out what works and using it to keep from having to do something they don't want to do. Also has to do with a rider that lets them get by with doing this.
