I don't buy it. Who's going to run around looking for a N2 top up when their tire is low? The important thing is to not drive around with underinflated tires, not whether or not you may have 10% regular air vs pure N2.
Introducing water is another thing. Even if you have regular air in your tires you should avoid poor quality air (moist). I've seen gas stations that had water dripping out of the air hose.
