Location may be used during setup, but only timing is used during normal operation.
Long version: When a new site is installed from nothing, it doesn't even have a name in the database yet, so it gets a sequential number. If several sites are being commissioned at the same time, the techs need a way to establish which one they're talking to. Querying the GPS timing module for its location is a good way to be sure you're not mixing something up.
But the site timing antenna is not necessarily on or even near the tower itself, they could be a hundred feet away. So the location used for location-critical services is actually surveyed in a separate step and programmed in as a site parameter that does not change. It's not dynamically derived from GPS during operation.
