I'd like to confirm that the Location setting on the Device Pool is active under all normal circumstances. I did some testing and it seems to apply to phones using that device pool unless the phones themselves have a location set. In that case device over-rides device pool.
What makes me hesitant is that a colleague of mine also tested this and found that the Device Pool Location just did not apply. Are there certain circumstances under which this setting is active and some where it is not? The section title is "Roaming Sensitive Settings" - does this apply to Device Mobility? We need to know if the Location setting on the Device Pool is a primary way of enforcing CAC (along with phone Location.)
