On my first hunt un Africa, after (I suppose) my PH had satisfied himself of my shooting skills, I generally went on stalks with my gunbearer alone. He spoke no English and I only the basics of Swahili, but we got along. With only the two of us, it was much easier to stalk (for example) past a herd of Tommies to get at the wildebeest we wanted. I never saw anyone, PH or otherwise, use the "PH carry".
