Or is the phytase unable to work on other foods phytic acid?
example, combining white flour - high phytase with nuts - high phytic acid

Generally speaking there is limited evidence that phytase naturally found in food (like wheat) can be properly utilized by humans to breakdown phytic acid. Thus people learned to develop ways of soaking and sprouting grains and seeds to make them digestible.
Also, there is quite a bit of research that shows that people who consume foods high in phytic acid (regardless of the presence of phytase) have lower levels of zinc, iron, and vitamin C (The studies I am thinking of are largely based off of vegetarian diets, so this could also be caused by lack of meat).
Ruminant and Rodents seem to be able to use supplemented phytase to break down phytic acid through a mechanism that humans can't due to our anatomy (it occurs in the rumen -- we don't have those).
All of the "science" behind digestive enzymes is very immature right now. And to look at enzymes across species is inherently dangerous and even less understood.
