Eric,
That cut was made with a saw blade, obviously, and saw blades make a saw cut (kerf) the same width all the way across the cut.
That angled cut means the top 2x as deflected in two directions: 1) bowed to one side, closing the cut up on the concave side; 2) deflected down, closing the cut up at the top.
Don't you love it when someone buys a new circular saw and becomes a 'carpenter' ... hmmmmm, if I set this blade all the way down, I know it will be deep enough to cut through that floor sheathing ...
