As a newbie to flyertalk, i apologize as i'm sure this has been asked thousands of times. For the OW Explorer, it says that besides NA, 4 free flight segments are permitted within each continent. If I go on Cathay Pacific from Hong Kong to Bangkok, have a stopover there and continue down to Singapore on the same flight number later, does that only count as one flight segment. Next, i'm pretty sure that it's allowed, but double checking to make sure that it is legal to do Europe-AUS (transfer in Asia) then fly back to asia and then on to NA in OW Explorer.

p.s. I originate in NA.
