This is Hara's writing style.
The first battle Moubu against Kanmei:
Kanmei knocked Moubu unconscious on the horse, then Kanmei suddenly said too much nonsense, allowing Moubu time to recover and counterattack.
-> Kanmei died
The second battle, Moubu against Man'U
Man'U knocked Moubu down with just one blow, then Man'U suddenly fell into a "nothingness" state, he waited for Moubu to recover to continue fighting
-> Man'U was knocked off his horse by Moubu, then left.
What do both battles have in common? That is, the enemy kept falling into some strange situation, at first they overwhelmed Moubu, then they gave Moubu time to recover, Moubu could gain more "weight" from the flashback, he remembered his memories with Shouheikun, then immediately recovered and counterattacked.
If Hara keeps this style, it can be concluded that Shibashou will lose to Moubu like Kanmei and Man'U.
