Take a look at the partial results of [this query](http://api.stackoverflow.com/0.8/questions/2544008/timeline?type=jsontext&pagesize=100):

    {
      "timeline_type": "votes",
      "post_id": 2544061,
      "creation_date": 1269993600,
      "owner": {
        // omitted for brevity
      },
      "action": "7 upvotes"
    },

I'm sure the answer pointed out by this record never had 7 upvotes and there are no similar records for other answers.

So what does "action": "7 upvotes" mean?
