Neuro PPRF lesion

PPRF controls lateral gaze of the ipsilateral side. From what I understand a right PPRF lesion should prevent the eyes from looking right and the eyes slowly shift to the left.
What I don't understand, is the medial pontine syndrome, if the abducents nerve goes, it also takes out the PPRF because its closeby. This for some reason causes both eyes to be forced to the ipsilateral side....How is this possible?? Shouldn't the eyes be to the opposite as in a normal PPRF lesion...?

In Medial pontine syndrome, the lesion affects abducent nerve, corticospinal tract, and medial lemniscus.
sometimes the lesion of the paramedian arteries may extend laterally and dorsally, and in this case it will affect the facial nerve, and PPRF, in that case it will produce ipsilateral conjugate gaze palsy, the eyes look at the normal side away from the lesion, and the patient will show drop of the mouth corner.that's called FOVILLE'S SYNDROME.
