By the stump I think its the case of a sloping backcut which all pros know make it fall against its natural lean.
Three cuts in the back cut, what a butcher job!
In regards to a sloping back cut. (For the record, I have never done one) Well it doesn't make it fall against the natural lean, per sa. It wouldn't make a difference if it was 180° from the fall of a natural forward direction.
In this case the tree ended up landing about 120° to the low/back side of the intended direction of fall
In cases similar to the same gravity pull with a traditional back cut then the tree may pressure *down* on a larger curvature without breaking the holding wood. In terms of an exaggerated slopping cut then it will preasure on the top/back of the lower/down side of the back first,, and which is becomes a 'sharper' point. Now it's leveraging off the one side of the point and is free to twist opposed to sit down .
Add wind to the scenario and it could be a big deal. I am pretty good at the physics of this trade but if someone can offer something different then I'm all ears.
--------
On a back lean, all of the above can happen with a SBC
The hack, really could be creating a leverage point. A bar pinch may contribute or combination with wind or inadequate holding wood.
A cut off tree with a reg back cut will start to fall slow and be consistent.
A back leaner will a SBC gone wrong, will quickly shoot off the stump and drop to the low side.

He obviously wanted to fall it that way for clean up purposes but there is levels to this game (not that this would be hard) and that boy is at ground zero. He would have been fine the other way.
This cowboy badly cut off half the tension side holding wood on a tree that had high potential to hit the house on that direction (if done wrong..which it was)
Once he fell the snipe off, he was on track to utilized the greater advantage .
That he did but fooked it up.
