I think the extra links were there all along but didn't show up until YOUR site gained enough reputation/trust for them to count. I have a strong feeling that links to your site that have nofollow are given full value if/when your site meets an unspecified threshold of trust. e.g. sites with affiliate programs are moving up the serps despite most incoming links being nofollow(which is ignored).
