Large number of lock with one of the session id in sql2005

I just trying to understands why one of the sessions could place around 700 000 lock ? I found this with a command below.

actually when is sql server placing a lo of locks compare to only 1 lock ? for example if we update one table with 1 millions of rows. Is this produced one or 1millions of locks ?

update tableB set columnB='Testing123"

SELECT request_session_id, COUNT (*) num_locks
FROM sys.dm_tran_locks
GROUP BY request_session_id
ORDER BY count (*) DESC
