Does a direct (multistop, same plane)
flight count as a single or multiple segment
if no stopovers are taken?

I'm contemplating the following 5-continent route, leaving from London. Is this a legal
RTW routing? The CAI-MAD, MAD-GYE and
SCL-MPN are direct flights, but have at least one stop.

( [xxx] are stopovers ):

Europe : LON-[CAI]-[MAD]-
S. America: [GYE]-SCL-[MPN]-SCL-[EZE]-
SWPacific : SYD-[NOU]-SYD-[PER]-[SYD]-
Asia : [BKK]-SIN-[BOM]-SIN-[DPS]-HKG-
Africa : JNB-[CPT]-JNB-overland-NBO-[MRU]-
Europe : LON
