I thought that if you put adsense code on both sites, then at some point a reviewer would say, "hey, this guy is trying to flood the serps for his niche".
Based on recent comments by others here, I now think that neither google nor google adsense really care about a publisher having multiple sites on the very same subject matter. The only problem would be duplicated content.
However, content that is written from scratch for site 2 could never be duplicate content in the eyes of the search algo since "duplicate content" is meant literally.
So, the benefit of having multiple sites would be...to occupy more territory as you wage your campaign.
More territory means catching more users. It also means crowding your competitors off the page.
