However, given that it was implied before that his clay creations contain Earth, it can be assumed that the Lightning techniques were to neutralise the clay bombs in some ways. I would have to guess that the bombs have chakra flowing through them that have an earthly quality to form them, which changes to explosion based chakra when he uses "Katsu" to explode them (Genno used Katsu to explode his paper bombs too in the anime, btw).
