Wdm? Zoro is flying(thanks to Jinbei) forward Nosjuro and attacking him, Nosjuro is just blocking the hit, and after that both Zoro and Juro was send flying from the clash. It wasn't the similar situation for Juro and Zoro. Basically this clash confirms
that Juro overpowered Zoro. Case if Juro was overpowered it would be only the Gorosei who was send flying, like Kizaru vs Marco:
