How does the motor config code work?

So I keep seeing things like

// VEXcode device constructors
motor MotorLf = motor(PORT1, ratio18_1, false);
motor MotorLb = motor(PORT2, ratio18_1, false);
motor MotorRb = motor(PORT9, ratio18_1, true);
motor MotorRf = motor(PORT10, ratio18_1, true);
gyro GyroA = gyro(Brain.ThreeWirePort.A);
controller Controller1 = controller(primary);

and my problem is that I keep seeing the “true”/“false” after each motor and can’t find any explanation as to what it means, if anyone can help that would be amazing, thanks!
