There's probably a KVO observer on isDocumentEdited; if nothing triggers setDocumentEdited then it doesn't know to check it.
updateChangeCount: says
If you are implementing undo and redo in an application, you should increment the change count every time you create an undo group and decrement the change count when an undo or redo operation is performed.
Note that if you are using the NSDocument default undo/redo features, setting the document’s edited status by updating the change count happens automatically. You only need to invoke this method when you are not using these features.
