You have to make three distinct squares, with some overlapping sides. You cannot really use a given stroke in two squares. And if you want to select these squares independently for selections; they will have to be separate paths anyway.
Now, if you want to be clever, you can do two paths: the vertical and horizontal rectangles (they will still have (partially) overlapping sides). Then the top left square is the intersection(*) of the selection of the two paths, and the the two squares in the selection of one rectangle from which you subtract(*) the selection of the other.
(*) In the Paths list, right-click first path and Path to selection, right-click second path and either Intersect with selectionor Subtract from selection
