Private Blog Posts Blocded from Admin

I thought the blog module was coded to allow admin access to user's blogs even if marked private.  Am I thinking wrong?  I am looking through the code in BxBlogModule.php and evidently I am misreading the code.  I am seeing it as"

if Visitor ID is admin or blog owner, then allow view.

However, I can not view a private post by visiting the user's blog.

This might be a silly question, but how do they even set blogs to private?

I don't see a "me only" option.

The blog is not set to private; the post privacy controls who can view the content.  If you note the title, it states "Blog Posts".
