I think it adds an appropriate flavoring to the original comment. He's not just starting a thread on the original, which would have been dickish. He added onto the criticism here of Dustin by saying that he'd heard a bad story, and thought Dustin's calling somebody incompetent was ironic considering the story he'd heard. Perhaps I have a biased viewpoint, though, because I was told a similar story that's been flavoring my outlook on this. It's not a story I'd say in public, because it's not mine to tell, but I've been having similar thoughts about Dustin through this mess, and I appreciate that they were stated. I also understand the need to be opaque when it's not your public drama. It's worth throwing in the sentiment if it's relevant, and in this case it is. Perhaps it wasn't inserted very subtly, but it deserves to be here.
