No.  Repeated level 'n' backups continue to back up the same data (plus
additions).  This has the advantage of reducing the recovery chain for
you.  Full, 5, 5, 5, 5, 5, 5   will mean you need at most two tapes for
recovery, even if you want Saturday's data.  

The 'incr' level is special in that it will only backup data more recent
than any other backup (including other 'incr's).
