Subject: That all depends on what AU model the PPC uses.

There are two main ones, the "all worlds are almost identical until something major happens" model, and the "the universes were never very similar, but they may have looked that way from a certain point of view" model.

In the former, famously used in Michael Crichton's book Timeline, any action in a universe that parallels another universe will cause a similar and/or equal action in
its parallels. In that model, the Agent DawnFire has bring in the Teselecta would coincide with another Agent in the Sundering Alternate Multiverse bringing in a Teselecta. Since there hadn't been a big enough split to distance the two universes from each other, both would allow the same event to occur from the same cause, though admittedly some of the details would be different because of quantum singularity and probabilistic matters.

In the latter, everything is genuinely different in each timestream. Chaos in decisions, motions, and chances has made it so that no event can be duplicated, and while similar events can occur, nothing can ever be exactly the same, with the same reason, and creating the same reaction, in two separate timestreams. In some streams, not much may appear to be different on the surface from another similar stream, because raw chance has caused an alignment of moments in a way that allows all of the important players to retain the same positions. Still, anything can change at any time. Universes following this model often have notoriously mutable timelines, since the appearance of a person in the past can have far-reaching ripple effects rather than having that person's time travel become part of a predestination cycle as the more rigid Timeline-style multiverse system would do.

Likewise, if the descendant of your two Assassins had found the Paladins, she would have found it in either universe, regardless of whether or not it was an AU, but the number of instances of that descendant that found the Paladins and the number of instances of Paladins that would exist to be found would vary depending on the type of simultaneity that's used.

... I like to talk about this sort of thing. Time travel, alternate universes, dimensional models... I can go on and on sometimes. A little late for the heads-up but... yeah.

I'm actually planning on writing a story set in the Mirror Multiverse, and the hinges of the plot are going to depend on which one of those is used for the PPC's multiverse format. I can make it work either way, but if it could be either, it would be a mess trying to make it fit both ways.
