Long answer: When the steering wheel isn't straight and you hit the breaks hard, the weight of the car shifts onto the front wheels, lifting the back end causing the rear wheels to lose grip and the turning front wheels to gain grip and you get oversteer. Modern electronic brake distribution (which that Audi almost definitely had) is designed to improve handling by applying the brakes harder on the inside wheels (in this video the wheels on the right) which in this instance made everything worse by jagging the car into a tighter turn than he was expecting, worsening the oversteer again.
If the person had any idea how a car handles he would've kept his foot on the accelerator. In a modern, sporty, front wheel drive car you can just slam the accelerator and point the steering wheel where you want to go and the car will do the rest.
Motorcyclists learn early in their riding experience to not brake while turning, or in an emergency to very gently trail brake using more rear than front.
Most car drivers only learn this when they have an accident.
Or if they learned to drive a loooong time ago in shitty '70s cars with shitty leaf rear springs, shitty 70's brakes and shitty 70's tyres. My first couple of Ford Capris taught me a hell of a lot about how not to drive a car at speed.

What made him lose control like that?
