Ahh okay, I understand now thank you.
But how does that help with anti-aliasing and anistrophic filtering? 

Well, anti-aliasing is one method that can be performed more effectively in eDRAM rather in the slower main RAM.

Another plus is deferred rendering; where multiple elements of a scene are rendered in separate frames then combined into one. This can be done better on Wii U (compared to PS3/360, anyway) because it's eDRAM is big enough to hold all the frames at once for fast, easy access.
