It works on the premise of convection. Hot air rises, cool air sinks.
It's the same principle with the temp of the fins. The higher on the fins you measure the temp, the warmer it is compared to the bottom of the fins.
Moving the thermistor up the fin means it's sensing warmer fin temps and will therefore run the fridge longer to get the fin temp down, which also lowers the overall temp in the fridge.
