I remember Superman getting 'offed' twice in the Justice League series, some puppet master or toy maker villain zapped him to an alt dimension while in another ep Doomsday did actually show up and they had a fight in a volcano or something, still not as confusing as this shizz.
It wasn't an "alt dimension" but the distant future after Vandal Savage used gravity control device that totally messed up the solar system.
In the
Justice League series Doomsday first showed up in "A Better World" where the Justice Lord Superman (which originally started out as a Crime Syndicate story but evolved into an alt Justice League decided to "fix" the world by conquering it and then come to our reality) lobotomized Doomsday.
In "The Doomsday Sanction" it is revealed that Doomsday is a flawed clone of Superman originally created by Emil Hamilton (who also created a clone of Supergirl that is called Galatea who Cadmus used as a super assassin and revealed in "Fearful Symmetry".) programed to hate Superman. It is never explained why Doomsday was running around to be lobotomized by Justice Lord Superman.
In "Hereafter" Superman is blasted 30,000 years in the future by Toyman where he meets Vandal Savage whose efforts to conquer the world resulted in the destruction of the human race as well as totally messing up the solar system (which is why the Sun in this future is red not yellow). Vandal Savage reveals that he has invented a time machine but it can't send anyone into the past who is already there. Realizing Superman isn't in the past (Superman reminds Vandal that he is "dead") he and Superman get the power source from the giant bugs that dominate a good hunk of the planet and Superman returns home.
So as you can see Doomsday and the "death" of Superman is not as simple as you make it.
