pretzel has nothing to do with getting onto the rail. its a FS switch up, FS 270 out.
As opposed to a hellen keller which is a BS switch up, BS 270 out. And then there are the variations of a K-Fed (FS switch up, BS 270 out) and the last one i cant remember.
A pretzel is still a pretzel if they spin onto the rail. eg. 270 on, FS, FS 270 out.
