Yup that is more or less how this fare worked. You had to have the first segment in a specific date frame. In this case it was a couple of weeks in December. After that flight could be mismatched as you like. For example you can take the first flight from BNE to Taipei after which you can make long stopovers and such. That stopovers also could be taken I'm BKK. And the same could be done one the way back.
As it was booking into C it seems that it has very flexible rules.
Basically it is after the first segment is flown all the other segment can be scattered thought the duration of the tickets validity.
