Is that bike on a stand ?.
There is very little movement going on there, there would be more suspension from tyre deformation than from the bush, hence why it may have done some miles.

If bushes such as that were effective in the way you are claiming, then we wouldn’t need springs or torsion bars, etc.
As BigSurfer says, bushes of that nature are there to absorb radial loads, as they do in automotive suspension.
We don’t use them for rotational control or damping, because after many cycles, the rubber or adhesive would fail.
Rubber usually best for tensile applications, such as our inner tubes.
