Other Addresses Available on Location Details page

Summary:

What is the purpose of this Other Addresses region on the Location Details page?

It is only visible/available when updating an existing location/viewing a location - and not while creating a new location.

The location address type values are "Location Override" and "Mailing address usage type" - I am curious what the intended purpose for these fields are? And how they integrate with the Shipping Details (i.e., Ship-to site, Bill-to Site, Office Site, and the option to select a designated received, as well as a Ship-to location in case the location is not a ship-to location)
