Well, he recovered didn't he? So, I guess must have done it right, all things considered...
Or is your issue more with the time it took for him to get it flying again?
Looking at the way the control surfaces were deflected during first recovery attempts and knowing that twins are not spin tested/certified, I do understand unease when looking at this video. Two more turns due to ailerons still in spin inducing position and elevator solidly NU, I'm not sure he would still have been able to get it out of the spin. This might have been a very close call.
