---- Some research on Google quality raters' behavior

Google does not strike me as a company that can spare two people for what seems such a mundane task.
It's my understanding that the human quality rater system (the big army that inspects specific SERPs) uses multiple human editors for each SERP - and therefore for each site on that SERP. It takes an aggregated agreement to establish the "editorial opinion parameter" that gets integrated with the automated algorithm's output.
The less mundane task is for those situations where either an automated "suspected spam" flag gets thrown, or there's some other human input that alerts Google to the site for some reason. I don't know if these engineers have the power, as one single person, to generate a penalty. But my feeling from watching Google and their quality control pattern, is that any opinion needs approval from a supervisor in some way.
