---- Big brands do not have the upper hand - Matt Cutts

They were two completely opposing pieces of advice from different departments at the same company. It had (and may still have) quite a few people's head spinning and left them not knowing what to do, because one was saying "go easy on the ads" and another was saying "you should plaster the page with ads".
They're not actually contradictory pieces of advice. Adsense advice basically says - if you want a higher click through rate, here are the best positions to put your ads. The spam team says if you put too many ads above the fold, we may penalise your site. If you look at both statements, they're not the "opposite" of each other.
edit for clarity: Adsense is just an ad publisher division of Google - they don't care where you get your website traffic from - they simply deliver ads for your website.
