Proof step 16 from proof bar-neq-soffset (previous step)

0 ≤ i - i0 ∧ i - i0 ≤ j0, getbytearray(r, i0, i - i0, st) + getbytearray(r, i0 + (i - i0), j0 - (i - i0), st) = getbytearray(r0, i0, j0, st0), i + j ≤ i0 + j0, i0 ≤ i ⊦ getbytearray(r, i, j, st) = getbytearray(r0, i, j, st0)

And obtained the following new goals

Proof step 15:
getbytearray(r, i0, i - i0, st) + getbytearray(r, i, j0 + i0 - i, st) = getbytearray(r0, i0, j0, st0), i ≤ i0 + j0, i0 ≤ i, i + j ≤ i0 + j0, 0 ≤ j0 ⊦ getbytearray(r, i, j, st) = getbytearray(r0, i, j, st0)
