Wrong. If the object is in a low earth orbit with this motion it would
have an orbit whose inclination is about 113 degrees. If the motion had
been from NNE by N to SSW by S the inclination would be about 101 degrees.

Had the motion been from NW by N to SE by S the motion would be prograde
at an inclination of about 68 degrees.
