The spacer fits on the clip under the spring perch (maybe some are different, but mine did: GS for Koni), so the spring's lower bound rests higher up on the shock. Higher spring perch clip position also does this. However, the spring is compressed by the shock assembly, so the amount of height introduced by the spacer (or clip) is not completely additive:
In parallel, from the lower mounting bolt hole to the top nut of the shock, you have:
Path A: the shock
Path B: some length of rigid material + a spring (+some cups and a rubber bushing, but we can probably ignore them as mostly invariant)
When we add a spacer, or use a higher clip. we are increasing the length of rigid material in path B. We are not adding height between the lower mounting bolt and the assembly.
This affects ride height, but it is not purely additive as the assembly length depends to some degree on the properties of the damper (shock). In the case of Konis (adjustable), this may be a function of the stiffness setting chosen (I used the middle setting).
There is a dangerous amount of energy storage in this assembly even when not on the car, so the spring is not simply compressed by the weight of the car. It is a parallel system.
The example of a spring weight scale does not have a shock damping it... or at least not such that when you lift the scale from floor to table, that the shock is still connected to the floor.
