the code is only in one room and you can also see in the clip that he was in the other room. if i were you, i would either write that in both rooms, or leave it in one room and in the other no idea, maybe a sticky not if you want but i'm just saying theoretical ideas here.
oh ok but i have to say that the code behind the couch is easy to miss that (the1st image) is most of the time what you see from the code If you don't move anything And just as an example The second image shows the maximum of the code you can see if you don't move anything
