AD8000&AD8001 PCB design issues

I'm designing AD8000&AD8001 for testing purpose. The AD8000's datasheet says:"Do not use ground and power planes under any of the pins of the AD8000." Is this means that I have avoid copper of the ground (or power) plane adjacent top layer? 


Below is my baord's layers structure:(Do i have to remove some copper of the Agnd1 just under the AD8000&AD8001?)

And here is the AD8001 and AD8000 used in my new test board:

Anybody can show me an example of this?
