Are self-approved PRs counted twice?

In Miri, I often self-approve PRs when I think they are sufficiently uncontroversial (which is most of them). The relevant commits and the bors commit with the approval then get synced to the rustc repo. If I understand the logic in this repo correctly, these PRs then count as one contribution by me for each commit, plus one contribution for the "review"? That doesn't seem entirely fair...
