That is true, by the object doesn't have to be stationary. Even if the object is moving, it can still be a reference point. For example, if a car is moving at 40 mph, then using the reference frame of a stationary person, it's going 40 mph. But if you have a bicyclist as your reference point going at 10mph alongside the car, it seems as if the car is only going 30 mph.
