It's not that unreasonable an assumption. Qualcomm offers a different opt-in service under the same name that does use location data.

Basically your phone uploads sensor data like cell tower strength and WiFi strength, and their service estimates your location. The your device locally uses gyro/accelerometer to fine-tune.
