This is because the roll only goes wrong in the second half
Too damn right John.
All vertical or semi-vertical manouevres occur in the initial pull-up. The second part which kills people is merely a consequence.
Isn't this like saying the crash only happens at the end? When the pilot stops flying in the middle of the air and goes to close to the edge?
Most accidents I have read about seem to occur at the edge of the air, where the sky runs out and the terrain begins.

this video of Bob Hoover with some interesting dead stick manoevres and where he pours a glass of iced tea while executing a barrel roll.
