The paragraph beginning with the word 'Suppose' describes the figure and does not imply that the the branes are coincident. Then the next paragraph supposes that they are. The second paragraph implies (to me at least) that the first paragraph describes the case where the branes are not coincident. I would also say that the figure can be used to clarify both situations as long as you suppose that in the second case, the branes are coincident even though they are not drawn that way.
