 Yeah it makes sense though.
The sage if the sixth paths did a similar thing.
He didn't die he simply ascended to a place to the point that he didn't  need a physical body any more hence why he was able to talk to naruto and sasuke in there thoughts when he needed to give them a power up 
The same applied to his sons by currently allowing themselves to reincarnate once their spirits ascended to the Astral plain.
This is also what obito did in the reverse by using the last drops of his sage of the sixs paths power to have his essence reside in Kakashi temporarily to give him dual sharingan during the 4th Shinobi war. Cuz remember all of what I listed comes from otsusiki that had the then tails in them or the offspring of an otsuski that had the tentails in them
