Of course it is possible (though not likely, given the current positions) that the opponent had already borne off one piece, then had two pieces "hit" (for some reason, I call it "huffing") to get them back out of his home board.
You're right, though, it is pretty close. If I find a spare few moments (because I'm sad) I'll write a little Excel thingummy to work out the average number of turns to completion for each player...
