Fizz's ulti does true damage?

"Why Cinderhulk Fizz?
Facing a Fizz is always an obnoxious endeavor, even in the top lane. His passive ignores unit collision and Playful Trickster (E) makes him untargetable for up to 0.75 seconds. Urchin Strike (Q) and Seastone Trident (W) add bonus physical and magic damage respectively, while his ultimate Chum the Waters (R) deals true damage before an area of effect knockup."
Typo or not? I havn't checked in on him recently.
