Select one or more names from the list of names to cause the filter to accept only tasks closed by any one of those individuals.

Since technicians can close any task, all technician names appear in this list. Since departments can close their own tasks, departmental users appear in this list.

In this context, Closed is synonymous with "deactivated". In other words, the user who marked a task as either Deferred, Non-Issue, or Closed is considered to have "closed" the task. (Sorry for the confusion.)
