Is my V$SESSION_LONGOPS view broken?

Check out the curious results below. Notice the changing SID-serial# and how elapsed seconds gyrates. None of the below sessions are in V$SESSION. The sql address and hash is not extant in V$SQL, V$SQLAREA, etc. (Note, we are using PQO with timed statistics.)

col SID-ser# format a10
col secs format 999,999,999 heading "Elapsed|Seconds" col addhash format a15 heading "SQL Address|Hash"

select substr(lo.sid||'-'||lo.serial#,1,10) "SID-Ser#",

        lo.last_update_time "Last Update",
        lo.elapsed_seconds secs,
        lo.sql_address||'-'||lo.sql_hash_value addhash

from v$session_longops lo
where lo.username not like 'SYS%'
/

                                    Elapsed SQL Address
SID-Ser#   Last Update              Seconds Hash
