Welcome! Here is the dumbed down version.

When at speed, if 4 cylinders can provide enough power to maintain speed, then it will only use 4 cylinders, thus using less fuel.

^^That's the long and short of it. The computer monitors speed and acceleration, then determines if 4 cylinders will do the job, then shuts down 1 cylinder in each pair. Started it in '06 I believe with most of the '06 HEMIs getting it, 100% in '07 on the hemi. It's only on the hemi, the 4.7L or the V6 down don't get it.
