Although "The Attic" is listed as 5V22, and "The Ghostwriter" is listed as 5V19, is it possible the latter was the very last season 5 episode filmed?

The thing that leads me to believe this is that in the latter, Ilene Graff's hair is noticeably curlier and wavier, like it would be in the next and final season. For comparison sake, here is a photo from both respective episodes:
