Yes, LONE5. You could also go CDG-MAD-JNB//NBO-xLHR-EZE-MEX-NRT//SIN-BKK-HEL-CDG if you wanted to avoid 2 of your 3 passes through London. That would only use 11 of your possible 20 flights (counting the JNB-NBO surface segment as one.) If you didn't return directly to France once you leave Asia, you'd still have 3 European segments available (and of course several African and/or North or South American segments too.) And with JAL in the alliance you could fly to mainland Asia before starting any overland touring.

Most often the "//" symbol means a surface segment between the two cities (e.g. JNB//NBO) and "x" before an airport code means a transit without stopover (e.g. NBO-xLHR-EZE.)
