Not sure what you're asking? If you're worried about "wasting" the HKG-LAX rt miles, you can take your number off the booking, requalify for GO with your intra-Asia trips, and then after your year ticks over you can retroactively claim the HKG-LAX trip. (But be careful since you can only file a claim up to six months after the flight.)

Remember that if you're already at the tier, you get a full year at that status. If you earn more than 60,000 miles again this year while you're already GO, your club miles reset at the end of your current year and then you get another full year of the status. It's different from what happens if you move up a tier, where as soon as you earn the miles for the new status a 12-(or 13-month) year starts immediately.
