Those are generally the steps for deep frying chicken, yes. Obviously you'd use home utensils and appliances, but brine -> bread -> fry is basically the only way you're going to get fried chicken.

I'm not exactly sure what you were trying to do with that link, but I'm pretty sure your intended outcome wasn't to show that KFC fried chicken is just like any other fried chicken, but with stricter recipes and industrial machines.
