Yup, that's exactly how they worked. I think if I remember correctly they dim from 100% down to 20%, which alters the colour in a sliding range from 6500k to 20k at 20% power. The people who thought these things were the bees knees had the idea that if you had them hooked up to a controller you could ramp them up and down over the course of the day like a sunrise/sunset, and that you could set it so that the yellowest time of day would be when you weren't home.
I kind of like that idea as I love how my tank changes over the course of a day, but with my LEDs even at their brightest and yellowest, my tank still looks like it has a 12K bulb over it. I suppose if you could get used to it, you'd get an even more dynamic tank, as you'd see your corals from 'full sun' all the way to 'super blue' every day, but I'm not sure I like the look of corals under natural sunlight enough to try getting used to it.
