How is Lemmy dealing with multiple communities on the same topic? (lemmy.world)

I come from Reddit and been enjoying Lemmy so far. How is Lemmy dealing with multiple communities on the same topic? To me:

If the communities are all active, then I shall subscribe to all of them, but end up having lots of duplicate/similar posts on my feed
If there is one community that is dominating, then what is the point of federation?

I was subscribed to android@lemmy.world, and just because I actively went into it, I saw a post that the community was frozen and they decided to use another android community on a different server, to avoid fragmentation.

That looks like something that could be done on client as well, doesn't it? I don't know if posts have UUIDs or something but maybe it can be done.

The problem is that posts may be exactly on the same trending topic, but not exactly the same. They could link to two different news sources for essentially the same news item. Or they could be a text or an image post about the same. Reddit mods would usually remove this kind of soft duplication within the same sub, and instead encourage to comment to one single post.
