I realize this maybe a dumb(ish) question, but I'm asking to make sure I read the sticky guide correctly.

Does a flight originating from SIN to MEL via SYD still count as the 4 qualifying flights?
My itinerary is as follows:

Singapore (SIN) to Sydney (SYD) — Fri, Mar 10
British Airways 15
Dep: 8:05 pm
Arr: 6:45 am
7h 40m
Boeing 777
Economy (H)

Sydney (SYD) to Melbourne (MEL) — Sat, Mar 11
British Airways 7449
Dep: 2:00 pm
Arr: 3:35 pm
1h 35m
Airbus A330

Thanks for any help! I've only ever had the 4 qualifying flights on BA metal.
