In a way, yes. Since Foo( ... ) # match any Foo according to constraints, if any Bar( ... ) # match any Bar according to constraints, if any these two patterns produce the Cartesian product, such as a nested loop does. BUT, the order of the pairings is indeterministic, and changes in WM might influence this loop, even make it infinitive.
