وَاعْلَمْ أَنَّ فِي جَمِيعِ هٰذِهِ الْأَقْسَامِ يَجُوزُ إِعْمَالُ الْفِعْلِ الْأَوَّلِ وَإِعْمَالُ الْفِعْلِ الثَّانِي، خِلَافًا لِلْفَرَّاءِ فِي الصُّورَةِ الْأُولَى وَالثَّالِثَةِ أَنْ يَعْمَلَ الثَّانِي.
Translation: The book allows governing by either verb across the patterns, while recording an exception: al-Farrāʾ does not allow the second verb to govern in patterns 1 and 3.
Iʿmāl means assigning government of the overt noun to a particular verb. Not choosing the other verb as governor does not make that verb meaningless; its required relation is resolved appropriately.
