Symmetry in Hardy-Littlewood k-tuple conjecture

Assuming Hardy-Littlewood $k$-tuple conjecture, do the "dual" prime constellations $(0,h_1, h_2,cdots, h_i,cdots, h_{k-1}=d)$ and $(0, h_{k-1}-h_{k-2}, h_{k-1}-h_{k-3},cdots,h'_i=h_{k-1}-h_{k-i},cdots,h_{k-1})$ corresponding to reversed sequences of prime gaps have the same...
