I've just been today trying to organize this area (decided I wanted the like container above the signature area rather than below with an image as a separator) trying to re-organize things. I just think a status in the signature area would add in unneeded clutter. Status updates displaying in the signature area would be a little confusing imo when you have your random text/quote signatures that some people have. Saying confusing, yeah the prefix says it's a status message but i still wouldn't like the thought of a status update floating to the left and a signature floated to the right/above and/or underneath.
That would mean you can't align the signature to left-side, so I don't think it's such a good idea placed there. Better option I think would be to include inside in the LIKES box (bar), but on a new line below likes.
