Berry's comment was about community perception. I don't think it was in reference to Watson needing help.
Are you saying that based on watching and listening live? Or based on the content of the tweet... I mean, reading the tweet and twisting it in my head, it might mean what you say but I think that is not the way it reads. He's talking first person Watson, says work is still needed and then reafirms the subject is Watson. First part is Watson by name, last bit is Watson by name - you'd have to take an enormous leap of faith to think the middle bit wasn't about Watson.
