What does Stage 1/Stage 2 at 45 degrees mean?

Checking torque specs on my WIS for the rear tie rod and noticed it says that on a 10mm x 1 the nm is 25 to the wheel carrier if a silver or blue connection type. If it's a 10mm x 1.5 then it's Stage 1 - 20nm then Stage 2 - 45nm at a fractional angle I'm assuming means 45 degree's. Can anyone elaborate on that? For the meantime I'm going to pick the first and go with a 25nm torque at the wheel.
