I don't think that's right. The stats are based on users' web browsers hitting the measurement points using an IPv6 HTTP connection.
It would be possible to fake it using NAT-PT, or a transparent HTTP proxy with IPv6 on the Internet-facing side, but I doubt that ISPs would be deploying hacks like that on a significant scale.
