The distinction is between Google looking the other way if AdSense publishers are making them money, and Google generating their own fake traffic on their own search intent inventory.

I'd say it's unlikely they are generating fake clicks on search ads.

Mainly because they just don't need to in order to make money. They can still just charge you for impressions on searches that aren't the most well matched. No need to create fake traffic like this blog post conspiracy says.
