As of WS Version 1.2.296 and Server Version 3.5.523, a new system variable has been added; _sessioncount. This system variable returns how many sessions/connections are open in SAP. The number will increment when a new session or connection is opened, regardless of the username or system ID.
Log in to SAP and note the title of the Easy Access Screen.
Open a new session or connection and note the title in either screen.
Note: If checking the original session, refresh the screen to see the updated title.
