Later on in the pattern, it says to sew the pocket linings to the inside of Left and Right Fronts. So maybe they are connected at the ends and you have to sew them in later. Without having it here in front of me, though, I'm not really sure I'm picturing it.
What I would do is just blindly follow the pattern. Maybe it will become clear then.
