I think we're getting tripped up on the wording here. As I understand it, this is what happens:
1. When there is a nofollow link on a page, the other, dofollow links on the same page still "count", but they DON'T get any part of the PR back that the nofollow link would have had. Originally they did, but not anymore.
2. At PubCon, Bruce Clay discussed some testing he did. He tested two links on the same page that point to the same target URL. Bruce said he discovered that only the first anchor text counts.
So yes, these sites described in the opening post may be trying to get that first link ignored hoping that a second link somewhere on the page gets its anchor text used as a ranking boost.
