It's not exactly "standard" composite, the bandwidth and carrier frequencies are different, but it's the same principle. For instance around frequency 0 (e.g. unmodulated), you have the luminance signal on a ntsc signal so that you can splat it on a B&W tv with barely any filtering, while a LD puts the audio there. The LD in practice has a larger total bandwidth than composite (8Mhz instead of 6MHz iirc) and they use that to separate luminance and chrominance better, which gives a lot less dot crawl.
