You have found it right. You also could have read it in
debconf-devel(7). You should also respect Policy 6.2:
| 6.2 Maintainer scripts Idempotency
| It is necessary for the error recovery procedures that the scripts be
| idempotent. This means that if it is run successfully, and then it is
| called again, it doesn't bomb out or cause any harm, but just ensures
| that everything is the way it ought to be. If the first call failed,
| or aborted half way through for some reason, the second call should
| merely do the things that were left undone the first time, if any, and
| exit with a success status if everything is OK.

- The config script isn't really meant to modify anything. You should
use it to figure out things, and the changes should be done in
- You MAY NOT MODIFY CONFFILES IN MAINTAINER SCRIPTS!
Please! read Policy section 10.7, especiall 10.7.3.
