I think the issue is that nuke uses a different coordinate system than AE. AE measures its coordinates from the top left corner of the comp. most other 3D systems measure from the origin which is the the centre of the "world". there are expressions that will convert from the AE coordinate system to the system you are using.

I don't have nuke in front of me but as far as I can recall it measures the Y and Z coordinates in an opposite direction from AE. so you could write and expression that reverses these Axis coordinates to compensate for the difference? Have you checked to see if there's a Nuke to Ae coordinate script available on the nuke Forums?
