Please explain the organization of the story. Why is it so confusing?

The first seven numbered sections form a story with two
parts. The first two sections comprise a short first part, with exposition and
complication leading up to a minor crisis, climax, and dénouement (the Swede departs
with Scully). The second part consists of sections 3–7, leading up to the fight (the
climax) and the departure of the Swede. Section 8 is a short narrative in itself, which
is climaxed by the stabbing and the vision of the dead Swede staring blankly at the cash
register. Section 9 is the dénouement, and it summarizes and unites the action. The
eighth section is brief because the story as a whole is more concerned with the
motivations of the various characters than with the details of the murderous violence.
The true facts about Johnnie’s cheating are withheld until the end because of the
story’s point that pride and reputation (which Johnnie would have lost if he had
admitted the Swede’s claim that he had been cheating) are stronger causes for action—in
this story, violence—than truth and the recognition of truth.
