This is of course because it's not so easy to lift a 10+ tonne vehicle as it is to lift a car.
Also a pit is safer in lots of situations compared to a lift.
A lift can collapse, a vehicle can fall from a lift, and, in this instance, the bushings have to be torqued in the riding position: If you want to achieve that on a lift you have to put a lot of pressure under the wheel while the car is on the lift. That is a very dangerous situation.

A commercial 2-post lift if correctly installed is not going to collapse even after 50 years. All certified lifts have safety locks.
To torque suspension bolts, I've simply used my under-hoist transmission jack under the wheel to load the suspension (at the corner of the car) where the torque sequence is required to set the bushings at the correct position. I just lift the corner of the car off the lift arm pad a few millimeters. No danger in using that technique.
