I'm thinking just a maybe on that theory. First of all, the signal for low tire pressure is the wheel turns faster than the others, not slower. Second, most people don't realize how much difference even 10% loss in air pressure makes on the rolling resistance of a tire. The sensor doesn't have to be too sensitive to pick that up.
On the other hand, the sensor and the bearing are an integrated unit, and you noticed the tire light stopped coming on when you replaced the hub. There may be a relationship.
