I think you might be right. I didn't watch the incoming notification email that closely to see whether it ever made it onto my BB. I'm testing it again but I'm betting you're right.
I know for sure that the notification screen on the FB app only shows the time that the email was received -- NOT the time the event happened. So if the email is delayed going to your BB, you don't get a real time notification from FB. In essence you are getting a notification via email which is triggering the icon.
It's probably a power saver as well -- I didn't see any manual for the FB app, did you?
