That is why the fandom doesn't talk much about that filler, it created a lot of plot holes and so much discontinuity. From Ashura using mokuton, to Indra's MS being the same pattern as Sasuke's.

But from what remember the "jutsu" that indra used to take down the boar was just using the lightning (like how Kaguya just disperses chakra when attacking) to take the boar down. And you may refere the fact that Kakashi's Chidori is the same thing which isn't wrong but i would guess that maybe Chidori is a more concentrated version if you will.

As for names goes, it was never stated anything about them
