He didn't just bring back Crisis stuff, Clark somehow only had memories of just having one child, Dinah and Rene weren't even involved in the Crisis but they have some memories back, and even if it was just Crisis J'onn still gave memories he didn't have, we saw Nash get back memories J'onn wasn't there for and J'onn had never met Dinah and Rene before this episode but somehow gave them memories.
