It’s not a special meaning — this would mean a request to break the dependency chain for the base temporal and spatial layer, while allowing higher layers to continue using reference pictures across this break. Figure 2 is a rough approximation of what’s desired, if you imagine it for temporal and spatial simultaneously.
