question about HMC: why do we need both modulator and slit?

I've been reading articles about HMC, for me the slit and modulator both create gradient pattern applying to the image, and they are conjugate to each other any way, why do we need both?

And the weird thing is, when the slit is mapped to modulator, the order of bright, gray is opposite to each other. Is this specially designed?
