Perhaps the confusion is the traditional labeling for a banana is listing water soluble fiber and not resistant starch while Dr Davis is focusing on dietary fiber.

Perhaps. But the traditional breakdown is labeed "dietary fiber." Wiki says that includes soluble and insoluble.
"Dietary fiber or roughage is the indigestible portion of food derived from plants. The consumption of foods high in fiber have been found to reduce appetite. [1] It has two main components:

  • Soluble fiber, which dissolves in water, is readily fermented in the colon into gases and physiologically active byproducts, and can be prebiotic and viscous.
  • Insoluble fiber, which does not dissolve in water, is metabolically inert and provides bulking, or it can be prebiotic and metabolically ferment in the large intestine. Bulking fibers absorb water as they move through the digestive system, easing defecation. [2]
...Chemically, dietary fiber consists of non- starch polysaccharides such as arabinoxylans, cellulose, and many other plant components such as resistant starch, resistant dextrins, inulin, lignin, waxes, chitins, pectins, beta-glucans, and oligosaccharides. [2]"

Bananas notwithstanding, I don't see how a quarter cup of hummus could possibly contain 15 grams of fiber while other legumes contains 2-4g.
