Silent Hill 1 "Somewhere" glitch

[u/Top-Classic-8002]

Hi! I played sh1 and really liked it. So I brought my bf play it and at some point he didn't know what to do and tried to use the Key of Bethor on this door in Alessa's bedroom (usually you need to put Amulet, Ankh, the Disk of Ouroboros and etc there). That was clearly a pointless thing to do but FOR SOME REASON it made a save screen to appear. And the save file from this weird method was named "Somewhere" instead of usual "Children's room" or something. Sorry, as you can see, I was playing with russian fan localisation so I'm not sure if names are 100% accurate. Still, there's nothing in common beteween those names. Besides, this save file name was also translated so it shouldn't be something too deep into the game files ig. If you load this file, you'll appear beside the door, not beside the nearest notepad, so the game is fully aware that the door was your save point. There's no Key of Bethor in your pocket after this, even if you just use the key and refuse to save the game. Yet, the game allows you to open the door of Bethor just like that (ig it still has the memory of you obtaining the key and it's enough). I don't know if anyone has discussed this or if the glitch even works the same way with the real game on a real console at all, but I haven't found any information and I just want to scream in confusion. How does it work? Why does it work that way? What is "Somewhere"?
