is one piece episode 562 filler?

Hody Jones is rejoicing in Vander Decken IX's defeat and Noah falling toward the island. Fukaboshi says that everything they have done to protect Noah's mission which began centuries ago, would be finished if the ship crushed the island.

There is then a short flashback to Neptune explaining that Noah is not just some old wrecked ship. Centuries ago, a promise was made with a "great man" to keep the ship on the floor and wait.

They have to protect the ship until that day comes. Hody then asks Luffy if he really was serious when he said he would protect everything.
