Are you talking about the logo on the front of the XA stem?? If you are, it is close to the same as what's on the 1R, with the XA having more material under the plastic black Cinelli logo disc as it is not punched through (except for small holes for locating rods at the back of the disc.) like the 1R, so should be stronger at that area than the 1R, but maybe the forcing from the split clamp design might still cause it to crack, unlike the 1R that has a clamp are without a split on it (a continuous ring around the handlebar)...
