 FACT: During the planes decent after shutting off the fuel pumps,  the altimeter is shown with the hands moving counter clockwise which  is normal in a descent. However, the altimeter setting (the small  window on the right of the altimeter marked 29.9, 30.0, etc) is also  moving. This is not an indicator, but a setting of the current  barometric pressure which is set by the pilot. It would not move due  to a change in altitude.
