Do I need set until sequence when create new db from primary backup

 Hi all,

   I posted article about Create new single database from standby backup and Shailesh help me solve problems at 2897214. Now, I want ask that: If I backup primary database use: 

   backup incremental level 0 format '...' database plus archivelog;

   And I use this backup to create new single db, Do I need set until sequence <seq_no> thread <thread_no> in RMAN script, just only (ofcourse, I restored controlfile success):

 

   run{

         set newname for datafile 1 to '...';

         ....

         restore database;

         switch datafile all;

         recover database;

   }

   rename redo logs success and open database resetlogs !

   Some links that I read about create new single db them also said about use set until seq... So, in my case, Do I need set until sequence when I restored controlfile succes, RMAN can know last sequence is backed up from this controlfile ?
