Re: decay
Kevin:
You cannot always catch decay in the tree by examining the face. It could be elsewhere, this would most commonly be the case in face cuts that are shallower than 1/3rd in.
Mostly the reason for boring vertically into trees that you suspect rot is to understand any weakness before you start your notch. With rot not always being balanced nor uniform in amount, understanding these flaws needs to be part of the fallers decision process on what can/should be done with a tree/snag.

Re: decay
Kevin:
"can't see a hollow or decayed tree splitting out into a barber chair without any stress in the middle of it."
Absolutely. With regard to the falling event, if the face ties into the rot it will function as a center face bore and further reduce the risk of a barber chair.
"What you can do is get down into the bottom of the trunk where the wood is sound."
Might be better stated as see if you can find a location where the wood is more sound to give you more to work with safely. Some species rot most commonly from the ground up. Root rot sponsored. Caution of course when working with any of these weak links.

Re: decay
You should easily see the formation of the wood in the face and hinge area after the notch has been removed prior to the back cut.
That's the specific area I was referring to.

"You should easily see the formation of the wood in the face and hinge area after the notch has been removed prior to the back cut."
Most of the time this will be adequate. You still could be in for a surprise on what is behind the visible hinge.
My primary point is that you need to know the rot situation prior to starting your face cut. If a faller puts in a face and discovers that his holding wood is good on one side and mostly rotten on the other he now has a tapered hinge etc. If he had determined the soundness of the tree prior to cutting he could have planned for this and made his cuts accordingly.
