Yet again,
No, I'm sorry, you are confused.
The length of the wrench determines the torque and is calculated from the handle at the end.
The left hand is just steadying the socket and it says so in the text, the physics dictate the torque is is calibrated to the length of the lever, not correct or accurate from anywhere else, only from the black handle part.
Again, quote from the link, article.
"Apply force to the handle only."
"The torque is calculated based on force being applied to the handle. Applying force on other parts of the wrench will result in a different torque value being applied."
Any fulcrum or lever is dependent especially on length so it obviously matters where force is applied so the value changes if it is not correctly applied at the proper handle.
Here are instructions from SnapOn and Matco.
