It's been resetting on me too, but I think it's a timed puzzle. That out of anything appears to be more likely, especially given how fast the above poster ran through each puzzle. The above poster with the video ran the first two puzzles in roughly a minute or just over. The third, if you notice, randomly reset a few times before they got it right, usually after they've gone roughly over 2min somewhere or when they hit a tile they'd already touched. The third puzzle appears to roughly need to be completed within 2min. I haven't tested this, as unfortunately I couldn't try to complete the puzzle due to freezing every 5sec which tends to happen if I have other processes running when trying to play Inquisition. Specifically processes that use my video card like looking over a video to ensure I'm following the correct path.
If it doesn't work when I reload, I'll try the tactics option someone else suggested. However I'm not sure how well that will work regarding that I need to jump to get around the proper way, apparently.
Anyway people on PC have been able to complete this puzzle because I know people on PC who have beaten the game, so it can't be perma bugged. It might be randomly bugged for just certain people too...that seems to be a running theme with this game thus far. However I think there's something we're not taking into account, and it's not companions. They don't activate or mess with the tiles, only the controlled character does. That much I have noticed. If you control Dorian, he'll activate the tiles instead and everyone else won't, you control your character the same, etc. etc.
Granted there is the possibility that it wasn't perma bugged until the patch came out, and with the patch the bug has only gotten worse. I'll report back once I've tested it out to be certain. Now to restart my PC and pray Inquisition doesn't want to randomly freeze and crash on me....again.
EDIT: YES IT IS A TIME PUZZLE. THERE IS YOUR ANSWER. COMPLETE THE FIRST TWO UNDER A MINUTE AND A HALF AND THE THIRD UNDER TWO AND A HALF MINUTES ROUGHLY OR SO. BASICALLY FINISH THEM FAST AND MAKE SURE YOU ARE ON THE RIGHT DAMN TILE.
Gods that was tense and annoying as all out, but I finished all three puzzles and only had to repeat the second one, where before I couldn't finish them at all. And that was before the game started freezing every 5secs and I was forced to google this questline to make sure I wasn't messing something up or it wasn't bugged.
So good news? Not bugged. Bad news? Timed really short and you can't make a single mistake or you're boned. Have fun trying to run through this like an insane person, try not to have a heart attack.
