That segment was never shown and was used specifically to prequel what is coming.

Similar cases have occurred in the anime but are usually filled in with filler. The story follows Luffy so when other characters go off and do their own thing away from him the manga doesn't reflect it.

With respect to the Edit: During the Dressrosa arc Usopp was one of the strawhats who stayed behind. IIRC there was an episode that had a cameo of sanji speaking to Usopp before things got too crazyin Dressrosa. It was when the coliseum event was still going on. We didn't see how the evasion happened but we did see that the ship was approaching. It wasn't brought up again until the Zou arc.
