This function doesn't reliably find all NPs within an utt, typically, it finds more, since it doesn't recognize complex NPs e.g. NPs modified by relative clauses, genetive NPs or PPs. Short NPs consisting only of a noun and immediately following another NP are analyzed as part of the preceding NP. The function is needed to predict phrase breaks, which are typically inserted after NPs, although they can also occur within complex NPs before NP-internal constituents, so the problems mentioned above are less crucial.
