People of the same height, have different leg lengths, different upper body lengths and different length arms.
Hence people of the same height, need different size bikes.
Also people of the same weight, ride differently to people of similar weight, they ride different areas, and they have different riding styles.
Suspension setup that is correct for a person, will be too soft or too hard for persons of very similar weight.
If people were all the same height/weight and rode identical trails, we wouldn't need different size bikes, adjustable suspension, etc. But the world is different all over, and people are all different, and ride with different styles, on different seasons/days of the year, at different times of their lives.
The point, adjustable suspension is a good thing, written guides, are only that a guide, starting point, as is advise from bike shops, magazines and websites. What is right for one person, is not right for another.
