The Active User Query View uses the ACTIVEUSERMONITORINGLOG table which only logs API calls. So, if a user doesn't do something that results in an API call, then they will not show as being active. If, perhaps, it was based on USERPAGEHISTORY or the logging was made more comprehensive, it would be far more useful and dependable. As it is, I'm not sure what value it brings.
