My best guess, to make the Hemmingway line unique. My second best guess... the first initial puffs are usually not meant for flavor but to get the foot of the cigar nice and hot, so why waste the first few puffs on a bigger guage when a smaller guage can get the job done just as well? I find the initial burn on hemmingways more uneven though (I probably just don't rotate the cigar enough).
