I think that what they're referring to is that After Effects' specialty is moving graphics, whereas Photoshop Extended deals mostly with stills (or frames of video, although not as elegantly as AE does). Although it's an irreplaceable piece of the Creative Suite toolkit, Photoshop was never meant to be the motion graphics tool AE is.
With the acquisition of Iridas, the powerful color correction toolset that makes Photoshop so good with still images, will be matched on the AE side by AE's new toolset. I assumed you were just kidding when I first read your post, but now I'm not sure, so I'm answering your question...
