- \ "___ \" - in the boot menu (SOMA)

In the game itself, the title of the chapter is not indicated in the downloads, instead it is - "___" -.
Yesterday I played and I had one length ___ for the entire passage, but having turned it on today it became smaller.

What does it mean? All sorts of ideas come to mind that if one day passes, the underscore decreases. As a result, if she disappears, something will be wrong with the ending of the game, such a prospect is frightening.

But it may be that in this way the game itself divided itself into chapters. Previously, the entire walkthrough was at two stations, the new save that I started today started on the ship, so this can indicate different chapters in the game.

Question: did the ribbon decrease in your playthrough? Did it depend on the date of preservation, or on which chapter at the moment?
