The reverse geocoded value can be obtained from the geopoint using pulldata("@geopoint",${location},"reversegeocode"), which returns the location as a JSON object. To extract only a specific value from the JSON object, use a pulldata function similar to the following, which extracts the Match_addr property:
pulldata("@geopoint",${location},"reversegeocode.address.Match_addr")
