Dialga and Palkia only did it in the movie for reasons. Giratina doesn't really care unless it bugs it.
Reshiram and Zekrom only did it because the heroes clash.
Kyurem is just empty and needs the splicers.
Xerneas and Yveltal were just the batteries for Lysandre's attempt to give back more to the community.
It's still rather weird to see the cover legendaries as mating partners though.
