Explanation

RMAN's IMPORT CATALOG command consolidates recovery catalogs. By default, it unregisters the database from the source catalog to prevent duplicate registration, unless the NO UNREGISTER clause is specified. The destination catalog is where metadata is imported, so it is never unregistered. Thus, options supporting source unregistration and the NO UNREGISTER behavior are correct.
