I feel some questions are more internal or rhetorical, perhaps, but I'll try to answer the best way I can. He didn't ask you to help, hence you're a "nosy" stranger. Some people get bothered by the actions of others, so maybe you care cause it's bothering you too? You have to touch his nose to restart cause you were already touching his nose for a successful input. Habits are loops as well, and we keep repeating those actions, so no, it's not a time-loop, instead an action loop. You can also choose not to stop him.
Again, I'm not sure if the questions were meant to be answered, but thank you so much for the feedback!
