That 5.2 Voodoo also has twin independent variable valve timing. Imagine if you had the capability, with a 360 for example, to swing your valve timing--intake and/or exhaust--25* from "zero"...50* total timing adjustment...completely variable. You'd get to change your ICL to bleed off some cylinder pressure under less than ideal conditions, or you could close up your LSA to enhance your mid-rpm torque.
The new LS and Hemis have variable cam timing, but you can't vary the intake vs exhaust events independently
