Are you looking at the latest version of the paper? https://www.cis.upenn.edu/~sga001/papers/pbc-sp18.pdf
It seems I forgot to update the eprint version a while back. I have updated the eprint version as well.

So, the 1st outer loop finish, ciphertext[k] = {Enc(2x^2), Enc(0)};
for the 2nd outer loop & 1st inner loop:
(1) C0 =ciphertext[0] [0,0,2,0], i.e., Enc(2x^2);
(2) C1 = C0 * x^-2 = [2,0,0,0], i.e., Enc(2);
(3) C0' = C0 + sub(C0, 3) = Enc(2x^2) + Enc(2x^6) mod (x^4+1) = Enc(2x^2) + Enc(-2x^2) = Enc(0);
(4) C2' = C1 + sub(C1, 3) = Enc(2) + Enc(2)mod (x^4+1) = Enc(4);
and the 2nd inner loop generate C1' & C3';
Nice job! I haven't found the pattern yet, but thank you very much for your reply
