Dropping Article On Transaction Publications.

In 2005 transactional replication, The following procedure worked (without dropping the subscription) when I dropped an article from a replicated database:

Drop article: On Publication Properties, uncheck the article (table, stored procedure or function).

Create a new snapshot.

Synchronize the push subscription.

DROP the article on the Publication and Subscriber databases.

Replication still works!
However, the following article says the subscription needs to be dropped and re-created when an article is dropped from publication: http://msdn2.microsoft.com/en-us/library/ms152493.aspx (Adding Articles to and Dropping Articles from Existing Publications ). For transactional publications, articles can be dropped with no special considerations prior to subscriptions being created. If an article is dropped after one or more subscriptions is created, the subscriptions must be dropped, recreated, and synchronized.
Under what conditions is dropping the subscription and recreating it absolutely necessary? I do not want to include this extra step.
