Two RMAN commands were run:
1. restore database until time 'sysdate' preview
2. restore database until time 'sysdate' validate header

According to Oracle doc, they both should produce the same output, but VALIDATE HEADER shows full or level 0 backups only.

Validate header does Reports and validates—but does not restore—the backups that RMAN could use to restore to the specified time.

According to Oracle Documentation:

       As an alternative to RESTORE ... PREVIEW, you can use the RESTORE ... VALIDATE HEADER command.
       In addition to listing the files needed for restore and recovery, the RESTORE ... VALIDATE HEADER command
       validates the backup file headers to determine whether the files on disk
       or in the media management catalog correspond to the metadata in the RMAN repository.
