If only this were true. If air gets in the system it can get trapped in the module. This can happen with routine bleeding, although unlikely unless you really don't know what you're doing. More likely it's when you're replacing a master cylinder or booster, both of which are upstream of the module. In which case you either need software to activate the ABS pump while bleeding or (I have heard) you can take the car out and panic stop, which activates the pump. Do that a few times and bleed again.
