EA SaaS Usage Report - Meaning of status Hibernated?

[ea0522]

When using the EA SaaS option in the cloud, we have a management option to view an "EA SaaS Usage Report".
This report shows an overview of who logged on at what time, as might be expected.
It also shows a "Status", in our overview limited to "Active" and "Hibernated".
Next to the column "Session Start Time", it shows "Logout / Disconnect Time".
The latter one is always filled, exept for the most recent sessions of each user.

The question I have is that I can't find the meaning of the status "Hibernated".
Obviously, the sessions without "Logout / Disconnect Time" have status "Active".
But the same status "Active" is shown for sessions disconnected long ago.

Can anyone explain the difference between statuses "Active" and "Hibernated"?
