Purpose of the "Links" section within Address API

Can someone explain to me what the point of the “Links” section is within the Create Address API Call?

My thinking was if I created an address for the student and included the parent User_IDs in the “links” section, it would automatically create the address on their record. This would ensure if a change was made on the Student's address record, it would update any record where the address was “linked”. However, the only thing I can see it does it allows someone through the User Interface only to then click “Add Address” and then select the address to be “linked”.

Is there not an API call that allows us to connect these without a user intervening?
