Functionality Question

Hi!

Quick question about functionality for this plugin and others like it. I currently have this one installed.

When someone comments on the blog using FB comments then it says it should appear on the Facebook post. Does this work the other way also? If someone comments on a Facebook post of a shared link to an article then should the comments show up on the “facebook comments” section of the blog article? If not, is that a possible feature request or is that not currently possible due to Facebook limitations?

Thanks
