It was only during the second time we heard/read anything with the beyonders that they tried to tie in the original omni-beyonder (or was it the cube retconned version after the retcon? either way they tried to tie in the original or retconned beyonder) with the beyonder's race which took place already after his initial retcon, so originally he was never a race or part of one. The new battleworld just seems to be using the tie in idea and are running with that version instead of the original omni-beyonder one.
It's still to early to really tell but so far that's what it seems like.
