CalendarStore question

I have recently added CalendarStore interactivity to a program I've 
written, but I'm confused by the documentation regarding 
notifications. In the docs for the CalCalendarStore class, this is 
stated:
"CalCalendarsChangedExternallyNotification
Posted by the shared NSDistributedNotificationCenter object...."
OK, but the notification seems to occur in my app's 
NSNotificationCenter defaultCenter rather than the 
NSDistributedNotificationCenter defaultCenter. My program works 
perfectly well with a plain old:

[[NSNotificationCenter defaultCenter] addObserver:self
   selector:@selector(myUpdateCalendarList:)
   name:@"CalCalendarsChangedExternallyNotification"
   object:nil];

Therefore, I have two questions: 1. What have I misunderstood about 
where notifications get posted? 2. How does the independent 
CalendarStore code send notifications to my program without having to 
use the DistributedNotification system? I reread the docs on 
notifications and still don't quite get what I've missed here. Thanks 
in advance for your insight!

Best Regards,
Dan
