They are different. If what you say were true about chakra Minato and chakra Kushina having gone to the pure land, then it would have been possible to revive Minato twice, one from his half in Shinigami that's currently running around and Minato 2 from the half in pure land that was in Naruto. That is obviously false. So all in all, Kushina never met grown-up Naruto, nor did Minato and Kushina ever reunite after their deaths in any form.
