Oracle will try the original expected backup location and then failover to the new (cataloged) location.  To prevent it from trying the original location that is unavailable, you should also CROSSCHECK BACKUP ALL (and optionally DELETE EXPIRED BACKUP ALL) so that it would mark the original location (/backup/DB/rman/20130623...)  as unavailable and not try it at all.
