I'm flying in and out of JNB on LH. From reading the rules it seems that I am not able to purchase a OneWorld Visit Africa Airpass- is this right?

I seem to see this in only one version of the fare rules out there (here) where it says:
"Travel on the last international sector in to Africa and the first international sector from Africa must be operated and marketed, or marketed by AA/AY/BA/CX/EI/IB/LA/QF"

This would be awesome if I could!
