Why does modifying the /var/confd/var/storage/cfg file fail to clear Last WebAdmin Sessions records?

The /var/confd/var/storage/cfg file stores configuration data but not the session log data displayed in Last WebAdmin Sessions. The research shows that clearing attributes in the cfg file using StorableEdit does not affect the displayed records. The actual session data resides in the reporting database and log files, much like how LDAP configurations are managed separately in the vSphere Development Guide 5 - LDAP.
