That is a hard lesson learned. Good thing it wasn't your last. It could easily have been.
Regardless of the lean, or PPE, what appears to be the main problem resulting in injury is you had chainsaw target fixation. Situational awareness is very important. Once that tree commits, get the hell out of there. No helmet in the world will protect you from being crushed by a tree. PPE is simply the protection part while cutting and remaining stationary. And, yes, it is very important. You were fine up to the point the work was done. All you had to do was run like hell. A helmet would have helped you in this situation, being aware and leaving the stump would have avoided the situation altogether.
I've had an oak do something similar to me. I let one go, and a limb smacked me so hard I lost my balance. I had a helmet, but that didn't save me when I fell backwards into the trunk of another large oak it was near, hitting the back of my head pretty hard. had I simply ran when the oak I was falling let go, I would have been fine.
Be careful out there. All of you.
