Hi Hraban,

I am not sure about what you say. The page shifting/creep correction is added individually per spread. If this is done correctly then the typeset area is on all pages the same width and has after folding and cutting  the same outer margin. 
As Wolfgang reports look into \definepageshift cum suis.


Kind regards

Willi

(This is called creep in English, Bundversatz in German.) That means, your outer margin will have different width, depending on the position of the page in its fold.
