When just created object is detached to pure pojo it gets temporary id . Real id is assigned only after transaction commit . This method tracks original document intercepts its id change and sets correct id and version into pojo . So it become safe to use such pojo id outside of transaction .

Core orient field resolve method relies on bound connection but it may be required to resolve id outside of transaction . So we use orient method under transaction and do manual scan outside of transaction .
