It shouldn't and didn't used to, but often does now.

Makers use the identical parts, except the band on a clamp-on font derailleur, so the position of the FD and it's range of travel changes according to the radius of the seat tube. Many modern FDs lack adequate travel to reach the outer ring on a 1-1/8" steel frame with textbook chainline, so you either have to move it in a few millimeters, or shim the FD outward.

BTW- the makers fix the problem by simply not offering 1-1/8" band FDs. Those who use braze-ons on a steel frame are left to their own devices.
