Daevid, I think there is only the initial connection (using mysql_query()), and the result set is saved to a variable. This variable is then operated on by mysql_fetch_object(). My problem was that the internal pointer had exhausted its original array when I was calling it a second time, and I had to reset the pointer with mysql_data_seek(). With that function, I was able to reset the pointer working on that same object (the original result set), without having to hit the db again.
