I think it means no judder since it effectively makes the monitor's refresh rate the same as the game's framerate up to some maximum.
A game rendering 45 frames per second is taking 22.22 ms to make each new frame; I *think* G-Sync can tell the monitor to just keep each frame onscreen for that amount of time. A traditional refresh rate of 60Hz means that the monitor HAS to refresh every 16.67 ms, so you're left with a choice between tearing where you give it two partial frames at once, or vsync where each frame has to be displayed for some multiple of 16.67 ms.
Yep, my understanding is the monitor will just hold the frame until a new frame is received.
