is one piece episode 504 filler?

Ace starts to care for Luffy more as a brother after he was nearly mauled to death by a bear. Ace then sets off on his own seven years later, bidding the mountain bandits and Luffy farewell.

Dogra comes by a few months later and shows Luffy a newspaper that talks about Ace and his new crew. Three years later, Luffy sets out from the Goa Kingdom.

He then beats up the Lord of the Coast for eating Shanks' arm and to show the results of his forest training.
