I'd guess (and this is a pure guess) if you look at the life expectancy vs. attitude and quantize the attitude on a binary scale (positive thinking vs. depression) you'll see a corralation between life expectancy and positive thinking. But what happens if we compare positive attitude vs. realistic (or "average") attitude?
It could be that negative attitude correlates with shortened life-expectancy, but once your attitude improves back to what can be considered "normal" there is no further advantage in being more positive. Kinda like some sort of "dimishing returns" situation?
