TPMS sensor ID uniqueness?

I haven't my TPMS sensors in my tires for some time now. Over a year at least. On the way home I must have drove past somebody with the same IDs because my TPMS light shut off, and stayed off for at least 5 minutes. It's the first time I've seen it do this since I removed the sensors. What's the likeliness that someone has the same IDs?

 

I doubt it can read signals of a car in another lane.

But interested nonetheless.

 

Possibly was a parked car or maybe someone in front/back of me? It's a route I drive often so who knows.

 

So the light has been randomly going out on it's own. Most often seems to happen shortly after starting the truck. Sometimes there's no other cars around, so I know it's not reading anyone else's sensors.
