This definitely is necessary for the "_v_" attributes that hold connections to a relational database. If such a "_v_" attribute is flushed, the next access to the DA (in the same request) reopens the database. As this is a new connection, it does not see the changes made by the previous connection (in the same request). This can lead to very nasty non-deterministic and almost ununderstandable errors.
