I think the quoted formua (5x sqrt) is even the optimum alpha-beta result, for perfect move ordering. So move-ordering heuristic can not be one of the reasons that current engine visit less nodes. This reflects they also prune nodes that in principle could affect the value of the root, if they had a very surprising evaluation that you could not guess from the branch leading to it.
