By the way, is it defined to go east, when you are exactly at the south pole? I suppose that either it is not defined, or otherwise it is defined as standing still.

Anyway, after the guy has travelled 2 km south, what if he finds himself at the exact distance from the south pole with the property that if he travels east for 2 km, then he is back at where he started (so the lenght of the latitude is 2 km). Then he can travel back north for 2 km to his hut.
