Nurbs (Curves?) and Birail 2 problem!!

I'm learning maya in college right now and i'm having a problem with a project at the moment.

I basically must use curves ( or nurbs I don't even know anymore ) to buid this completely. I have to build this thing:
and i'm at the part of Birail 2 , this here:
Also, i'm sorry the tutorial are in french but following the images should be enough to understand my problem I think.

So far, I can do the Birail 2 on 1/4 of my cylinder form however I can't Birail 2 on the second 1/4.

It's basically birailing on the other 3 quarters but not the quarter that I want.
Please help!!!
I've been learning to use polygons and I actually got very comfortable with it but suddently my teachers told us to forget everything about polygons and learn nurbs instead. I'm about to pull my hair out.
