Yes, as I understand the system, the VVT is infinitely adjustable, not binary (fully retarded or fully advanced). Cam advance varies with at least RPM but possibly also perceived engine load though that is speculation on my part. Just like the secondary throttle plates, it is not an 'On / Off' system but one of variable change.
What makes it a bit hard to fathom is that the valving looks like 'bang- bang' control (as a toaster- oven: the element is either On or Off but bouncing between the two creates an effective temperature band), which it is, but with the hysteresis built into hydraulic systems, it really translates to a step-less, variable system.
There is another system out there that does VVT from Suzuki and that is also very interesting: it is done by using 3D camshafts. Instead of a profile across the entire lobe of a camshaft lobe being the same, Suzuki uses a varying profile across the camshaft and then moves the camshaft along its own axis to alter not only the advance of the cam(s) but the actual cam profile regarding duration! A very interesting and effective approach. Compared with a C-14, the only choice is the timing of the cam profile start; the profile itself is ground into the camshaft and cannot be altered.

The only document I've seen says it is "stepless", I took that to mean it was infinitly variable (in theory, but possibly is only as variable as the cam sensor output is variable).
I'm not sure if this came from a Gen I shop manual or perhaps a KDS operation manual, but it appears genuine Kawasaki documentation to me. (I'm easily fooled.)
