Not working alter system audit?

Good afternoon, I noticed a strange thing, no information is logged about the murder connection.

1. audit alter system by access
2. select SID, SERIAL#, osuser, machine from v$session where username='user2';
3. alter system disconnect session '72,1224' immediate;
4. select * from sys.aud$ there is nothing about the murder connection
