It's recording our location at that time to inform Almighty to take care of us easily.
When you go out of station, we inform our family members our location at regular intervals.
When a parcel or letter sent to us by a person, the delivery agent sees state, district, town/city, area, street and building finally.
Same we inform in sankalpam. Jambu dweepE, Bharata varshe, Bharata khande - for example, letter came to Bharata khandam. Then a place between 2 rivers, then the side ( intercardinal direction ) of Srisailam. Sacred Srisailam is central point known to Gods.
Once we inform our location, it will be easy for God to help us in case of emergency.
