In essence, every social media platform leads to political echo-chambers in the long run. People build their own social networks consisting of people they know personally or admire, this easily leads to being surrounded with people that share the same political bias as you. I don't believe that healthy political discourse is even possible on social media in the first place. Especially not if the political posters are anonymous. The advantage with Fediverse and Lemmy in particular, is the fact that creating multiple accounts on left-wing/right-wing/neutral instances is pretty easy. You can add all your Lemmy accounts to a (web) app like vger.app and voila you can now join every political discussion on Lemmy in an almost seemless experience. Political control is thus harder in the fediverse than on centralized platforms like reddit or Twitter. But even if the platform managed to discourage political segregation, the people will still look for every possible to segregate themselves.
