You've done a good job of describing the barber chair phenomenon. As
you have learned, a dangerous situation exists anytime one is cutting
a tree, log, or even a branch that is under tension. Binding the butt
of the tree can prevent most barber chair accidents, but just as you
wouldn't knowingly place yourself in line with the muzzle of a firearm
just because the safety is engaged, you should never place yourself
(or any part of your body) in a direct line with the direction of
tension.
