There's a couple of ways I'd interpret that non-answer, but I absolutely don't see that as a confirmation.
"I don't know the answer, but I have to say something." Or "The answer's no, but this rumour goes in our favour of convincing people to switch to 10 so we're not going to deny it."
If it said "Windows 10 will remain up-to-date indefinitely", then I'd agree.
