Boneworks question and spoilers

near the end of the game when [spoiler]you are about to enter the void. right after the time tower battle, you need to smash open a boarded up door. right before that there is a VR helmet that if you put on is different from all the others, see pic. It's purple and there's writing all over the walls. The puzzle grafiti is on there indicating there might be some sort of puzzle to be solved, with the words UP and DOWN but DOWN scratched out. [/spoiler] I'm not sure what this means, but is there a possibly a hidden puzzle here that's hinting to the solution? I'm not sure what I'm suppose to do.
