Wow. Just the changed mindset (compared to the present, at least) would be amazing.
"Are there others out there? Yes. And they're like us. We should try to meet again some day."
It's almost like a modern day Atlantis myth, but true.
If you want a really interesting setting for a game/book, imagine a major regression on Earth (standard post-apocalypse trope), and the colonists finally find a way to visit again...

By the time we managed to meet them again, there would be no reason to expect them to be like us.

This is a regular feature of Motie civilization in the series beginning with The Mote in God's Eye.

Depending on technological advancements and how "hard" you want to consider your sci-fi or future science (purely based on likely developments of current technology, etc), how close to Earth conditions you want to assume the other planet was, how much you believe humans are still evolving, whether you think humans are likely to evolve along similar paths if segregated, whether we are considering mental models only or physical likeness...
So yes, no reason necessarily to expect them to be, but some small chance depending on a lot of factors lining up.

Yes, it's not an original trope. The rogue star explanation is one of the more feasible I've heard though.
Wasn't this sort of the idea behind the Homeworld games? Ancient artifact discovered in Antartica, left by the original settlers of Earth, leads to a quest to travel "home".
