I'm reasonably confident that the tiger shark in question wouldn't have mouthed the observing diver, had it not been an orchestrated dive.

I appreciate your view of this. Its interesting, that, with my upbringing and background in a family that spent their life in the woods and back country with these animals, I feel quite the opposite. I would rather deal with a predatory mammal way more than a 1200 lb shark that wants to taste me. More than likely, it is due to exposure and input over a lifetime of being in the environment of these creatures. Probably the same reason why you feel the way you do as well. To me, the similarity with both situations involve humans in the creatures habitat, baiting with food to bring them in, and watching while they feed. That mixture leaves the door open for injury to us, the weaker species, regardless of which creature it is that we are intruding on.

In places where people do see tigers in unbaited conditions, like Cocos Island, the advice about staying on alert still applies. They are ambush predators and whether they've been spotted does a lot to determine how bold they get.
That second video of the original incident shows that indeed those pokes at the shark are slightly uncomfortable to the shark but actually almost completely ineffective at stopping the shark if it decides it wants to bite. I don't think that's a revelation but confirms there's really nothing between you being bitten or not but the shark deciding it doesn't feel like dealing with a couple of prods, though luckily it seems to decide it's not worth it more often than not. I cant see real well but note the poles design is made to apply more surface area and not harm the shark but also means it's not very pokey if they need it to be though again even that would be incidental if the shark was determined.
Whether in the ocean or on land, it's only that the predator doesn't feel like dealing with the relatively slight damage we could inflict on them, short of using a gun type weapon, that prevents an attack and our demise or serious injury. I met someone yesterday who was showing pics of grizzlies eating salmon in Alaska with a selfie of the bear close behind the photog. I was thinking if the bear decided to be so inclined it would be 1_2_3 boom they would be on you and then could do as it wished.
As someone mentioned you can see the stress the "handlers" must feel because the first guy pushed it and it just turned and did what it wanted, then he had to swim over to try to effectively persuade it to stop. Having to try to go hands on with a massive shark, when everybody else would run the other direction, must be pretty mind boggling and you have to give it to these guys that do this job.
HalcyonDaze comment about the sharks feeling being influenced by whether it can come from an ambush position is also very interesting
I think it depends on which tiger sharks. Just like people, there are bad people, good people, aggressive people, layback people. Here are examples of layback tiger shark in Cocos:
Also in Cocos, there are killer whales that would hunt on tiger sharks.
