The ball joint swivels it doesn't matter when it's torqued.

The rubber bushing doesn't swivel. The rubber twists. If you torque with the wheels floating you will twist the rubber when the wheels are loaded and then over-twist when you hit bumps. Keep that last bolt loose enough the bushing can swivel until the wheel is "loaded".

I do while the car is on stands by lifting the wheel hub until that side of the car floats just a bit off the stand. If I'm being pedantic that day I'll disconnect the sway bar link as that will slightly reduce how far the wheel hub will travel.
