My understanding of the RTW rule is that the itinerary have to head in a specific direction either East or West orientation. With that rule in mind, is the following itinerary considered valid:

SFO-YUL-FRA-OSL-AES (stopover)
AES-CPH-ZRH (stopover)
ZRH-WAW-NRT (stopover)
NRT-TPE (stopover)
TPE-ICN-SEA

Will the NRT-TPE, and TPE-ICN be considered as backtracking?

What about the following itinerary?

SFO-YUL-FRA-OSL-AES (stopover)
AES-CPH-ZRH (stopover)
ZRH-WAW-NRT (stopover)
NRT-BKK-SIN (stopover)
SIN-ICN-SFO

Is it considered backtracking, going from NRT to SIN, then SIN to ICN on the way to SFO?

Thank you in advance!
