Yes
"Again pardon me working through a sour mash fog but do you mean that you DO NOT use a bore cut when you know or believe that the tree has significant rot or decay?"
===========
Yes, at least for the most part.
several thoughts here.
1) you risk a pinched bar,
2) trees with significant rot that are vertical can collapse. I've never seen it but I fear that. For most this is a time to step away if there is any concern but in some instances the back cut from the rear, if there is something of a solid rind to work with can be wedged. (Usually the best call here is equipment or driving with another tree.)
3) Rotten trees and hollow trees are very low barber chair risk. The need for a bore back cut isn't there.
============
Staying away from a boring back-cut on a tree with splitting potential is also a thought.
I would suggest that the thread cited earlier was on a tree that didn't barber chair but split when blown over.
Splitting trees can twist and there can be a loss of directional control, so they are dangerous for sure. Just not as dangerous as a barber chair - where there is one primary split that moves the fulcrum up the stem.
