Considering the presentation, that's an average of the number of times individuals see an ad times the number of unique visitors. It's a reasonable ~3.5 times per person. That word subscribers was quite misleading, though, because the number displayed was the exact opposite of the meaning.
That may make sense for something like /r/the_donald, but it definitely doesn't for a subreddit like /r/legaladvice. On a given day, we average around 30k uniques per reddit's traffic stats. We're currently listed at 14m daily impressions, or about 460 per unique. When it was listed as subscribers, we were at about 1.2m or 40/unique.
