Hyundai service manual for strut assembly reverse installation states: "Tighten with specifed torque at curb position of vehicle"

What is curb position? Is this the same as curb weight?

I was looking into changing out the struts on a 2015 Hyundai Accent and noticed this caution note at the bottom of the procedure.

If this is referring to curb weight, does this mean tighten the bolts, then put the weight of the vehicle on the axle, and then torque to specification? And is this for all bolts (axle mount, and upper mount in engine bay)?

If so, what's the best way to accomplish this without the wheel on?

Also, what is the reason for this? Just to better understand.

Here is a link to the procedure I'm using: manual

This means that the final torqued setting has to be done with the vehicle sitting on its wheels so the suspension is in the "normal" position. So this can be on the pavement or when on a ramp but the mass of the vehicle must be taken by the wheels.

If you tighten the bolts/nuts with the suspension "hanging down" then the rubber bushes end up "stretched when the suspension takes the mass of the vehicle and stretched even more when the suspension flexes which leads to premature failure.

To avoid confusion for some, the type of ramp I am referring to is shown in the image: enter image description here

These are common in some countries and also used for vehicle testing in many establishments. These ramps are installed with the metal surfaces where the wheels go level, which is useful as trying to find apiece of perfectly level ground can often be a challenge, even a concrete driveway is usually constructed with a slight slope to promote drainage.
