Feddit.dk and any other Lemmy instances do show Mastodon upvotes. It’s not Feddit.dk-specific, it just so happens that Feddit.dk has a couple of comments that went super popular on Mastodon. It’s just random. Maybe try reading the post again, it sounds like you misunderstood something.

Yes, I’m definitely not understanding something. You said that Mastodon only sends upvotes to the instance of the user receiving the like, in this case feddit.dk, right? Then why, if I view the post on feddit.dk, does it not show me those likes/votes? What is dependent on my instance?

I don’t understand what you mean, how does it now show you the likes? If you see the two comments here and here as I linked above, you can see the high upvote count. Almost all the upvotes are from Mastodon instances.

Sorry, I mean when I view the comment via my instance. I don’t understand why my instance needs to receive the votes/likes directly, instead of my instance fetching them from feddit.dk when I request the comment.

Your instance doesn’t pull the upvotes from other instances. That would not be scalable. How would it know when to pull again, to see new upvotes? When would it stop pulling periodically? Never? And you’d have to do this for every single post and comment everywhere.
No, instead ActivityPub uses a push mechanism here. So any new activity is pushed out to the ones that are deemed relevant to know about the activity. Any other instances are unaware.
