I watched that a dozen times... tried the trick but it didn’t work. I have had luck in the past using Alphabet left handed drill bits just slightly smaller than the base of the threads. If the bolt didn’t catch, a dentist pick can turn out the remaining metal stuck in the threads... not in my case... they were the worst bolts I had ever seen....

I've used the technique on stuck parts and can vouch for it's effectiveness.
