IIRC the criteria for this are actually:

 1. No conffiles in the package.
 2. No postrm script in the package.

Since purging consists only of running postrm purge and deleting
conffiles, a package that meets these criteria does not need anything
done to be purged, so removing it sets its state to purged.
