The miles needed is the same whether or not TPE-HKG-TPE is included, assuming that HKG is transfer only on both ways. For TPE-HKG-LAX-HKG-TPE, though, there is a difference.

This is incorrect. If you get an agent who miscalculated the miles required for your trip, you should call MPO to get a refund. However, it is true that the OLCI will be messed up, even though OP can choose to only upgrade on certain segments.
