I'd like to understand a little more about this.

This image was taken with my 65mm lens. The camera was pointing down, and I had some tilt in the front standard, also forward. I was using the stairs as a focus point.
If you enlarge this image and look to the very bottom, you can see that the top of the tread string is in focus.
As your eye travels down, the steps go out of focus.
The timber grid and weeds are out of focus.
The boats, however, are back in focus.
Now I just don't understand how the 'wedge' of DOF created by the forward tilt of the front standard, creates an area which is out of focus, more distant than the closest object, then returns to similar distances further up the image which are back in focus.
What have I missed?
