Those concerned with the geometry are thinking too much.
The reason the torque wrench should be at 90 degrees to the nut wrench, is that 90 degrees negates the extra length of the nut wrench. If it is not at the correct angle you are effectively lengthening the torque wrench and increasing the mechanical advantage (over-tightening)
