To connect to a hidden service (.onion site) your computer connects to a random relay, called the rendezvous point and stops there. Then, it tells the server to also connect to the same relay using Tor. The server chooses 3 relays and sets up its own connection to the same rendezvous point. This scheme means the server stays anonymous. You have absolutely no clue where the server is. Even the owner of the relay 188.8.131.52 has no clue where the server is (or where you are).
Your computer knows which relays it chose, so it can display them, but it doesn't know which relays the server chose.
(How does it tell the server where to connect? The server connected to a random relay called the introduction point and then it published that relay's address in the Tor directory service. Your computer connects to the introduction point to tell the server about the rendezvous point. Why not just use the introduction point for the connection? Because that would overload the introduction point if the server was busy.)
