The Association label needs to be functionally useful to utilizing workflows so a record with a specified association label can have an associated object’s information transferred only to it and not all records associated to it. Specifically when an deal needs contact info for independent billing and shipping contact’s info that is unique to the specific deal. if the association label changes the assocated record fields should be able to change to reflect such. Otherwise using a property value for the contact enrolls a workflow for all records with an association.
