Two exact same notifications when a blog post is published

An employee received two notifications (at the exact same time) about a new blog post yesterday. She is subscribed to the blog and has selected to receive email notifications when "Posts are added to blogs I'm subscribed to". I'm trying to figure out why she got TWO notifications. Variables:

1. I ghost-posted the blog post for the author, and almost immediately after posting, I made a quick edit and republished. Then I did that again when I spotted another error. So two edits within a minute of posting. I thought that might be the reason but then I found this resource which seems to eliminate this variable. A blog edit shouldn't trigger a notification, right? (+) When do notifications go to Subscribers? - User Documentation - Verint Community 11.x - Verint | Telligent Community

2. The employee in question has been designated as a blog author for that application. Is that a factor?

3. There are no comments on the blog or any other activity. 

Any guesses as to what's going on here? Other than #2, I'm not sure what other factors to test.
