WHy do they use 2 gears back to back on this mechanism?
It's called an anti-backlash gear. There is also a small spring between the two gears. It puts tension between the two sets of teeth so that there isn't any play between it and the gear it's mated to. If you've take it apart be sure to add a little to the two gear before assembly.
