"Reflected inertia" is a term of art used in mechanical engineering.

In the present context, it means the effective inertia of a load as seen at the motor.

Sort of like an 'effective inertia', which is different because of the mechanism in-between?

So as you gear the load down (motor turns faster than load moves), the reflected inertia would be lower at the motor (because the mechanical advantage is greater than unity) right?

Right.
