How does downvote disabling work between federated instances?

Context: I use Liftoff as my mobile client. I have accounts on blahaj.zone and lemmy.world. When I'm logged in on blahaj.zone on desktop, there is no downvote button. It appears on Liftoff.

I understand that downvote-disabled instances don't accept downvotes from downvote-enabled federated instances, but does this work in reverse? Can beehaw or blahaj.zone accounts downvote content on lemmy.world, etc?
