It looks function composition to me.   g(f(x,y),h(w,z))  where they,
say, swap around the order of f and h in g.   In that way the evolved
boolean network must evolve to remember how g, f, and h work
independently to be efficient and coping with changes in ordering.  
Intuitively, it makes sense that changing the composition of functions
from time to time would make each function be more robust.
