Are they though? Not really.

The case you could make is that the first group of Pete's World Cybermen seen in series 2 continue a clean narrative all the way through TV: The Next Doctor. The Cybermen from RotC/TAoS enter the main DWU in the series 2 two-parter, and then they end up in Victorian London through the events of series 3. We can clearly say that's all the same group of Cybermen.

But other than that, there is almost no way to tell if a group of Cybermen who look like the 2006 variants are from Mondas or Pete's World. Any stories outside of those boundaries that are on the Pete's World page are there out of speculation -- there's no proof that the Cybermen in series 5 are those from Pete's World, and in fact most Cybermen stories to use that design in recent years have not taken an issue to the idea of those Cybermen being Mondasian.

We can confirm that there's a direct narrative of Mondasian Cybermen who left Mondas and Pete's Worldian Cybermen who left Pete's World, but once they're out in the universe there's no way to tell who is who. And since the Doctor considers them one species with various origins, we should as well.
