Yes, you need xOWE4 to visit South America.
Also is a transit considered a segment? if not does that mean you can do 4 segments, and do unlimited transits as long as your within the 20 flight limit?
20 flights limit means 20 flight coupons, 20 boading passes, or 20 flight numbers for whole your trip.
Even your flight contains some stops, one flight number means one segment.
For example, QF1 SYD/LHR 1stop at BKK.
If your itinerary is SYD-LHR and one flight coupon, it is one segment.
If you go SYD-BKK-LHR and two flight coupons, it is two segment even you just transit at BKK.
