This is partially incorrect, it wasn't just the exercise that hurt him, it was the fact that he did'nt stretch the one time as he did all previous times. This is why he emphasizes the importance of stretching. His injury was also not permanent. Good mornings should be done with lighter weights and proper form, as should any exercise.

ya, then he recovered and became even better than he was before lol

Troll or doesn't know his history.
