They can only see cached posts from before the defederation, and nothing new from us.

They can post in those threads though, but they’re not talking to us in them even if it looks like it.

they can’t see our posts & comments, actually. defederation goes both ways, the only thing they can still see of us is cached threads from before the defederation. these threads are effectively dead like a plant disconnected from it’s roots, in that new posts & comments to them don’t go anywhere. & we can do the same thing, go back a few days & you’ll still see lemmy.world posts here.
