The small print at the side of the page says 1 flight equals 1 flight segment so I think 5 or more flights gets you 7500 miles. I am doing a EDI- AMS-MNL return so the extra 5000 miles will come in handy especially after the mean 25% mileage they have given me. My next flights are after April so I will miss out on the full 7500 miles not unless I get a cheapo Cityjet flight to London City and visit the London for day before the promotion runs out.
