If poster can't be bothered to offer a summary then I can't be bothered to watch the vid.
The device can add inertia to the suspension travel without adding very much actual mass. If the suspension is thought of in an electrical analogue, we have inertia (inductance), springiness (capacitance) and friction (resistance). The designer will normally have only C and R to employ in his suspension components, and the availability of a compact L allows more complex impedance networks to be used, with possibilities such as increasing isolation of the chassis from wheel deflections.
Imagine the state of electrical / electronics engineering if no one ever figured out the notion of a "floating" inductor, and designers only ever used inductors with one end grounded. The invention in the video adds "floating inertia" (or differential inertia?) to the vehicle designer's toolbox. It tries to keep two objects in a state of relative rest or relative motion with respect to each other, unless they are acted upon by different forces.

I suppose the invention of high inertia without high mass is analogous to discovering high permeability cores.
