Without any source whatsoever other than what I can dream up (which is better than some unnamed chief executive), I think this is bullshit. Bill Gates is now looking at building a reputation worthy of Mother Teresa PLUS Andrew Carnegie; why does he need to be CEO of Microsoft again.

Maybe if the stock price was going to completely tank, which would affect his foundation, he would consider coming back. But the stock shouldn't do that; the company is still remarkably profitable.
