How to randomize the focal blur samples in animation,
because they are identical in each frame.

In example, whene there is low quality (in example 5 samples) then
the "dispersion" / "diffuson" pixels are identical in each frame (in the
object do not move), while I expected them to in example jump around
randomly like a true noise should.

Can this be fixed?

Not directly, and probably by design.
Some thing you can do is add some small randomness to the confidence, variance, 
blur_samples and aperture.
confidance must stay <1, so the random range should be chosen acordingly.
variance must stay greater than zero, but small.
In an animation, use the clock and/or the frame_number to change the random 
stream seed.
