Why would Toneri exploding make the chakra go back to Naruto? Past examples of this?

Having it in the Shikamaru Hiden does not prove regenerative chakra, it would prove that he either had some left over from his fight with Sasuke/undoing IT or asked for more after undoing IT.

Toneris absorption is a fairly reasonable reason for Naruto temporarily losing 6PSM as well.
