I'm not sure I entirely understand why reduced predation risk but increased resource limits causes this? Maybe it's because tool use increases yield of valuable food, and so for effort expended a higher food outcome against the pressures of resource starvation come into play.
But, the thing is why does reduced predation pressure apply? I am guessing that finding tools, and using tools on the ground is a higher risk activity, focussed on the short range, less time spent scanning for predators so more "risky" if there are more of them around.

Being under reduced pressure from predators means they can spend more time on the ground rather than hiding in trees. The ground is where the rocks are.
