Yeah... that's what I thought... the VTEC secondary lobes can only increase the lift or duration of the valves opening, but with high RPM NA applications, this is a no brainer positive thing to have...
It would be crazy if the VTEC could shorten as well as increase, but that would take some weird-ass servo-articulated system or such... or something like the BMW Double Vanos system...
