SQ Tier Points earning

Having had a look at some of the fantastic trip reports regarding SQ's F service, I was thinking of the number of tier points you can earn. It's possible that I'll become VS Gold later in the year and was planning the renewal already [:I]
Looking at the tier point earnings table, you get 7 points for an SQ F sector greater than 2000 miles. So, would I be correct in saying that you could do LHR-SIN, SIN-MEL and back and earn 28 tier points for it? I've assumed that these are always treated as 2 sectors. If so, that's a Gold renewal nearly done....
Thanks,
David.
