Yes, but the fact that PPO can learn very long range strategies with enough computation when most would expect it to diverge/fail to learn at all is already demonstrated by the original 5x5 DoTA bot. That's probably the same thing there: it can handle the long-range learning and so does fine at human-level APM, while the SSBM AI is stuck learning short-term strategies which heavily rely on simple reactive fast policies.
