Below VTEC each valve is controlled by a single rocker arm. Note that in the video you can see how the two valves open and close at slightly different times. The center rocker also rides up and down on its cam lobe, but it is not connected to the two rockers that open and close the valves. It just moves up and down without doing any real work. Then, when the VTEC pins are pushed through the rockers (by oil pressure) all three of the rocker arms are locked together. Now the two arms that open the valves have to follow the center rocker arm, which is following the hotter cam profile.

I hope that helps, but if it's not clear please feel free to ask more questions.
