Self-Winding Automatic with Double Barrel Balance Wheel.

Have recently purchased and since recieved a Thomas Earnshaw Observatory with a Self-Winding Automatic with Double Barrel Balance Wheel movement, I'm well aware of the brand the fact that is considered a "mushroom" the false history all of that stuff, I'm just hoping someone may be able to explain to me in the most simple way possible how this movement works cause it seems like when i wind it one way the left wheel will rotate which moves the right wheel which then moves the seconds hand but it seems sometimes when i wind it back the opposite way it cancels out and the right wheel stops rotating, which in turn stops the seconds hand from moving?

ANY help would be greatly appreciated!!
