I kind of question this at a first read, but admittedly my knowledge of S & R dogs is limited.
I would question this since I wonder if "fear" truly has a unique smell . . . I mean I suppose people who are fearful are releasing more hormones and endorphins such as adrenaline which may accentuate their unique smell, but I'm guessing that most people who get lost don't start out fearful (i.e. the curious kid who wanders into the woods, the boy scout who wanders off trail, the senior with dementia that wanders into the woods near his home, etc.)
If I had to hazard a guess I would think that the dogs are trained to track a person's particular scent (often from a recently worn item of clothing) and that the dogs would be able to narrow down their search in an ideal situation when those bodily smells are accentuated by the hormones (both the "good" (think when you are wicked happy and having a great time) and the "bad" (think fear, hatred, anger, etc.) hormones that would be produced in any emotional event.) If this were the case I would also suppose that someone who did not exhibit a high level of these hormones (such as fear due to someone who has autism or Alzheimers or some other type of mental impairment . . . or even someone who simply is not showing high levels of fear, enjoyment, etc.) would be harder to track.
