You can see in input.cxx:
if ((fabs(axis_values[j] - a.last_value) > a.tolerance)) {
(...)
a.last_value = axis_values[j];
(...)
}
With my yoke stopped, with js_demo i see a lot of lines as:
| 0000 -0.0 +0.1 +1.0 -1.0 -1.0 +0.0 +0.0 . |
all of them without changes.
So autopilot may change axis values (because my yoke is not noisy) and
this difference (position 0 of yoke and autopilot setting) may be greater than
a.tolerance, so it vibrates (I think, correct me if it is not correct).

When I do not touch my yoke it does not pass any event. So there may be
another problem with it. Please probe it by your own keeping your
joystick stopped
(test it with js_demo or something similar). You will see what is my problem.
