Because if you are shooting for 95 lb.ft and you are using torque only, you have to be in the "vertical and straight" part of the steel traction curve above.
Every friction change is going to give you a very different clamping force. As you know, it does not take very much angle to increase the torque. The bolt barely turns. This is due to being int the "vertical and straight" part of the curve.
You have absolutely same lack of inacuracy during pre-torque if you are shooting for a pretorque of 80ft.lbs. Your inaccuracy due to friction means that you have an error of angle of maybe 15 to 30 degres.
But you are going to ridicule this error of 15 to 30 degres by turning the bolt 120 degres or similar during angular thightening. This way, you are in the stretching zone of the bolt. (curvy almost horizontal).
Now, lets say that you had an error of 15 to 30 degres at the beginning, it would not matter, because you are on a "horizontal" curve, so strain is very similar.
