Lifting the body meaning your lifting on the sprung portion. Lifting from the axle is unsprung as the suspension is above your lifting point. When you lift from the bumper/frame/fender/rocker whatever, you are lifting from above the suspension which means you're fighting the springs as you work. In theory the chain wrap would offset this, but not nearly as much as not having to dick with it is.
I've had enough sketchy situations with my hi lift I ended up buying an aluminum floor jack from Hf and kept it in my truck box. The handle comes apart and I have 3 tons of lift whenever I needed it. Just kept a hunk of plywood to keep it from sinking.
