Yes, that is how it is designed. The only events that are excluded are "Pending and Deleted". Right now it will display Open, Closed, Awaiting Settlement and Settled events (because all of those can still be posted to via comments). Wouldn't be that difficult to add in some options that admins can choose which Event Status will showup (so if you only wanted OPEN events, you'd uncheck closed, awaiting and settled).
This has been implemented and will be available in the next release.
You have 3 options now (see the below image). This option effects the "Find New", Event Read Marking, Sportsbook Node Block (new events count) and the New Events Bubble on the Sportsbook Navigation Tab. The default setting (the first option) is how it currently is configured, so nothing has changed in that regard.
