Could someone explain this rule in the Global Explore to me:

BACKTRACKING BETWEEN REGIONS AS DEFINED UNDER
131N . APPLICATION IS NOT PERMITTED.
132N . EXCEPTION - ASIA MAY BE PASSED THROUGH
133N . TWICE PROVIDED THAT ONE OF THE DEPARTURES/
134N . ARRIVALS IN ASIA IS A TRANSIT WITHOUT
135N . STOPOVER IN CONJUNCTION WITH TRAVEL
136N . BETWEEN THE SOUTWEST PACIFIC AND EUROPE.


Are the regions TC1,TC2, and TC3? or are they the continents as decribed in the OneWorld Explore fare? Specifically i am wondering if i can do:

HKG - JFK(stop) - EZE (STOP) - MIA - IAD (STOP) - LHR (STOP) - HKG


I know the two NA stops are not permited under the OWE, but are the allowed under the GlobalExplorer. For the matter since there is no "2 NA entries with one as a transit" exception would i be forced to fly from SA straight to EU?
