Why would Kishimoto tell Pierrot his backstory plans? He didn't even do so officially in the manga, i don't see the reason for a sudden change of heart.

More likely, he simply gave some pointers, considering Ashura's pseudo-rasengan and Indra's Pseudo-Chidori make no sense whatsoever, since no transmigrant ever invented them.
