Do we have any way of knowing that Yong-Gang Wang of Google is correct about this?

I think it is highly likely that he is correct about this. Professional spammers will likely monitor the effect of their campaigns closely, so would know about this first. I would expect less wiki spam if rel=nofollow was actually honored. Especially hidden (unclickable) links don't have much value apart from page rank.
