The final paper doesn't mater. If you are in the area, you can skim the paper and look at a few key graphics and tables. Those key graphics and tables should be in the initial draft, because the rest of the article is build around them. Perhaps the final graphs will be prettier, or they will fix some minor errors (like a missing label).

(Sometimes it's more complicated. The initial and final version have bigger changes because the writer realize it's better to select other examples instead of the initial ones. But in this case I guess they don't have too many examples to cherry pick.)
