Those two gears are the output gears. They're free-spinning. The shifter dog couples one or the other to the hex-shaped output shaft. There are two other relevant gears on the "power shaft" that engage the output gears; they are hidden directly below what you can see.
There are two or three other gears that transfer the output of the motor(s) to what I've called the power shaft. They provide a first-stage reduction from the motor speed, but they aren't involved in the shifting.
