To a discerning eye this pattern looks like stronger minds implementing higher quality tree search[1], either through implementing higher quality neural search heuristics for tree pruning or via greater search depth.
Given relative NP-hardness of the problems[2] we are usually dealing with at our line of work and what we know about planning in machines and animals[3], it doesn't look immediately implausible.
With planning capability strong enough, one doesn't need trial and error in the real world for moderately complex problems: the plan devised through internal search is good enough to work on the first try. Weaker planners have to compensate by executing more rollouts and using the real world as a ground truth model.
