Why do Facebook Wall-To-Wall comments appear to be from the recipient?

Here's an example screenshot (I blurred names for privacy). In the Yoono sidebar, the message in question (A Wall-To-Wall post) appears to be written by Kimberly because it's her face & profile that's associated with the message. But in the main window is the actual Facebook Wall page that shows that the message was really posted by Sarah to Kimberly's Wall. Just seeing the message in the Yoono sidebar is confusing because you can't tell who actually posted it and would assume it's the person who's face appears (who is actually the recipient of the message, not the sender).

This screenshot was with the Firefox Yoono Sidebar version 6.1.1. The problem appears the same on the most recent IE Add-On (I believe also is 6.1?) On another computer I updated the Firefox sidebar to 6.2 (or whatever was available for download on Yoono's site on 8/29/09) to see if the problem still existed. The same post was still credited to Kimberly (instead of Sarah, the actual writer), but the message itself didn't appear in the Yoono sidebar; only the "Read..." link which takes you to the actual Facebook wall page. I haven't had a chance to see what it looks like with the Yoono Desktop App.

Thanks for your help. Let me know if I can clairfy anything...I hope I'm explaining the situation right.
