maybe its becasue it is the grand line. i mean Zoro was a bounty hunter, bounty hunters need good direction to catch criminals. maybe his sense of direction wasnt so bad in the East blue becasue, though he may not have been associated with the islands they were on persay, he could know that becasue of the direction of the wind blwoing this way is east or something. like a give way to give directions. like where i live the wind usually comes from the north west, so maybe becasue of how the east blue is set up the wind can give direction and he may have already been on some of the islands (like usopp's or the one they met nami on) becasue he would face criminals on various islands
