nofollow does not actually mean "do not continue your crawling any further from here" but, rather "do not count the links included in this page as *votes* for the linked pages for the effect of link popularity". Tim Converse "translated" nofollow in "untrusted/non-endorsed links on this page". Therefore, the crawlers will surely follow the links included in this page.
As explained by Tim Converse (Yahoo) and Brian White (Google) in one of the 2006 PubCon Las Vegas conferences, the name of that directive is unfortunate and deceptive.
