NOAUDIT create session for a specif user

after executing

noaudit create session by MY_USER whenever successful;

my audit destination is still plenty of audit file regarding logon of MY_USER

i.e.

LENGTH: "431"

SESSIONID:[9] "562277048" ENTRYID:[1] "1" STATEMENT:[1] "1" USERID:[14] "MY_USER" USERHOST:[8] "myhostname" TERMINAL:[7] "unknown" ACTION:[3] "100" RETURNCODE:[1] "0" COMMENT$TEXT:[140] "Authenticated by: DATABASE;AUTHENTICATED IDENTITY: MY_USER; Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=xx.xx.xx.xx)(PORT=35529))" OS$USERID:[5] "osusername" DBID:[9] "dbid" PRIV$USED:[1] "5" CURRENT_USER:[14] "MY_USER"

is that correct ?
