The rule referred to is about Back shifting and it is commonly followed in indirect speech to maintain tense harmony: main verb(reporting verb) in the past, all other verbs (reported verbs) must also be of past view point. However, there are situations where natural sequence of tense is more important. So we are taught not to change the tense if the main verb is in present/ future tense i.e, we are assuming ourselves at the point of time of the main verb(reporting) and use the tense of the verb as one would have used then.
However, Wikipedia in an article on indirect speech holds that it is also possible to use the natural sequence even though the main verb(reporting verb) is past or conditional.
