At line 655: "... In a sparse filesystem it will be the sequence of powers of 3, 5, and 7: ..." So I think this means three = pow(3, 0);

  Doesn't explain why it's not 1, 1, 1 or 1, 5, 49.

    It does, you're just not paying attention. The comment appears over the function that uses those variables; it's not 1,1,1 because they want to hit 1 only once in the sequence 1,3,5,7,9,25,27,49,81,125, etc. It doesn't explain why it's not 3,1,7 or 3,5,1, but that's because there is no reason for that.

      The full comment in the source explains it fine, but that's not what I'm replying to; who's not paying attention here? The abbreviated quote I was replying to just confuses things by leaving out critical parts.
