From this entry, not from the index: Its red-over-white bicolor half echoes Indonesia's flag, though the crescent-and-stars canton makes Singapore's design otherwise distinct.

Computed at build time: each flag is rasterised to 64x48, and the score is 0.55 × colour overlap + 0.45 × structure. A different weighting would rank these differently. How the index works.
