Unfortunately, this is a limitation of nearly all nutritional studies.
Partly we use mechanistic evidence to separate cause from effect--that's part of why the article goes into detail about, e.g., how soluble fiber binds to bile in the liver. If there's an association between A and B, and a known physiological mechanism where A causes C which causes B, it makes it more likely that ultimately A is the cause of B.

Nutrition science has lots of those and needs more. In an N=1 intervention study, I too found fiber to be health supporting, but that wasn't randomized or controlled.
