Within the boundless Rivers of timelines, each River representing all the countless timelines within a single Reality.
All the timelines of all the world's that could be found within a single Reality, with some worlds having beings powerful within the Time Influence, or had powerful Time related Unique Skills.
Thus the branches such a world would have, were many. While some worlds had Deities, who had the authority of Time, to the point where their mere existence branches out time itself.
Thus each river being formed by countless timelines was not an exaggeration. And the number of Rivers here, were likewise countless as well.
And this was all within one Chaos, how many Chaos were there? Probably countless Chaos as well, then countless Greater Chaos as well... leading to Boundless Rivers of Time.
