That's not the issue. If you think about it bit closer: Shake = rapid velocity changes. Eliminating shake = trying to keep velocity constant -> no acceleration. WE all (well most at least) know the basic formula: F = ma (Force equals mass times acceleration). When we eliminate acceleration, there is no shake, hence no force if needed to move the IS group. What it does have effect on is the point when the "free space" where the IS group can float runs out and it has to start moving, then there is strain between the IS group and the lens body.
