Well, let's say that you don't have the same schema in both databases.

Attaching two databases allows you to do queries across multiple
tables and would require much more effort if you maintained separate
connections.

e.g.

SELECT People.name, Pets.name
   FROM
        People AS People
        other_database.Pets AS Pets
    WHERE
        People.id = Pets.owner_id;

It would be less pleasant to do that query via multiple connections.
