Didn't poof like a clone >_>

Also according to BZ the Greatest, both the clones that entered the first dimension disappeared due to not having enough chakra?

no. naruto went into a different area. only the real naruto has truth seeking balls. when the real naruto went in, obito also got in with kamui. the clone obito kamui'd in got curvestomped by kaguya.
