Each Community can decide how they are surfacing replies in a thread/topic that were marked as a solution. The Samsung Community decided to surface them right after the first topic starting message. This is often done to allow any readers to quickly find the answer. Because the reply that was marked as a solution is moved out of the discussion flow context there is a link "View solution in original post". This link will take you to that message within the conversation so you can read previous and subsequent replies to get more context.
In the example topic you provided this is rather boring, because the solution was already the first reply message. But picture a large topic spanning multiple pages where you otherwise would need to paginate through all the replies.
