In Jojo, there's only one universe being reset, and it was literally the best they could make out of a bad situation where the badguy murders the active cast and was in the middle of resetting the universe anyway. Not to mention, they're not "dying" as much as they are being reborn with several influences in or out of their lives.
Here on DBS, two characters fuck off to another dimension while literally everything else dies, including the souls of the people who already died.
The badguy(s) literally got what they wanted. This is like if the Freeza saga ended off with Goku beating up Freeza, leaving him on Namek, and Freeza gets his wish anyway.
