We like to be mr grumpy, don't we :) Let's give the authors some credit.
Seriously, who said that there's a single set of inputs that is needed to have a given outcome? Take the fight scene in the video: you can see the player missing some of the events (they flash red) and being hit with an iron pipe in the ribs because they didn't dodge. But maybe in the end you can win the fight anyway... except that it will take longer efforts because you're hurting.
Technically, that would be forking and then merging again narrative paths.
As for there being one "best" outcome, maybe that's something that will bring a completionist playing the game again and again to find the best paths all the time in all the scenes, but is that different from people making no death speedruns of Super Mario?
Actually in this case part of the enjoyment of the game might come from not playing it "perfectly" and exploring the narrative twists that follow.
