I believe Robbo is just referring to the various theories on time travel in general which in fact contradict one another. Here's how it is handled according to Omni 01's cosmology:

The self-consistency principle is somewhat implied to exist already according to the origin of the Harbingers. The self-consistency principle should also work just fine to connect the various time periods without the aid of parallel universes. All time paradoxes would be stabilized, and would not threaten to destroy the universe.

There are other parallel universes in Galactic Crucibles, but they do nothing more than to serve as holding places for older ideas that have been retconned out. In canon, they have no direct connection to Omni 01, and they only exist because of the many-worlds principle.
