is one piece episode 325 filler?

While the rest of the world is finding out about the Straw Hats' new bounties and events at Enies Lobby, Blackbeard is seen reading an earlier account of the Straw Hat’s activities at Enies Lobby, commenting that their bounties should rise afterwards. Lafitte wonders if the Straw Hats hijacked a Sea Train from Water 7 to get to Enies Lobby.

Van Auger comments that Water 7 isn’t too far from the Blackbeard Pirate’s current location and thinks they’ll cross paths again while Doc Q suggests that fate may allow them to meet again and take action when it happens.
