is one piece episode 701 filler?

In the town of Spider Miles in the North Blue, a 10-year-old Law sits alone in a trash dump and is told it is time to eat. Seeing Corazon walking along, Law stomps on one of his cigarette butts and curses him before being interrupted by Senor Pink, who tells him that Donquixote Doflamingo wants to ask him something.

However, as Law claims he also has something to say, Corazon picks him up and throws him into the trash heap again before walking away. Seeing this, Senor Pink notes that Corazon has no mercy as Law swears to kill him.
