Different situation all together. The weights are added to the
individual wheels to compensate for imperfections in manufacture or
arising due to everyday wear and tear. The weights are different simply
because each wheel/tyre combination is slightly different. Without them
the wheel would vibrate when rotating at high speed putting undue stress
on bearings, suspension and steering, in extreme cases making the
vehicle undriveable. This effect is most noticeable on the front wheels
as the driver can feel the vibration through the steering.
Equipment to balance the wheel/tyre combination has improved over the
years but balancing has typically been done off the vehicle. Doing it in
situ is I suspect largely motivated by the reduction in time taken by
obviating the need to remove/replace each wheel. I've never seen one in
action. There may be a slight improvement in the end result, I don't
know, as there should be no or little imbalance in the actual hub/brake
disc. Maybe someone else can be more definitive.
