What is this sum supposed to mean?

it is from a paper about boolean functions (https://eprint.iacr.org/2007/290.pdf))

My best interpretation:
> The inner sum isn't really there
> They include it to show they are treating the binary representation of i as a vector
> because deg g <= deg f, the terms in the sum with nonzero coefficients will only have d or less set bits
