Watching that video either the pilot was spastic or that is the normal way to fly by side stick. I had one ex Buf, B52 pilot,fly like that with a yoke but no one else. Normal pilots don't move the controls unless a correction is required, they don't move it all over the place for no reason.
I'll probably get shot down by a real 'Bus pilot, but as I understand, that stick deflection in the 'Bus is essentially commanding a rate, not a control deflection. Zero control deflection equals zero rate.
As such you would be pulsing the control rather than applying a pressure.
