VVT on L99, or what?

I'm looking at the cut away illustrations of the LS3 and L99 on
Compare the timing gears/chain on the two engines. The LS3 cam gear looks like you'd expect, but the L99 looks much different. It's obviously more than just a timing chain cam sprocket. Is it part of the AFM system (don't think so), or some sort of VVT mechanism, or what?
