I'm pretty sure this is to improve the crowd-sourced database of WIFI AP's. Google was involved with Skyhook for a while and there's no reason to think they stopped using similar tech. It's really that simple: war drive to build a map of AP to location, remove any that seem to move around (ie trains), and then you can use the database to map an AP sighting to location in the client. Trilateration on signal strength for extra points. Source: worked with them.
