That is indeed unusual Gretchen. The stem is gold plated, not just on the outside, but on the inside also and there is no insulation inside the stem. It will still retain full contact in that situation although it is not intended by any means.
It just occured to me…the 4.5 is tapered from .006" wire which is how thick it is at the stem. Bending it to an angle gives you quite a bit of leverage and surgical stainless is very tough. It is nearly impossible to twist so it can stand the rotational force to overcome the crimp. I wouldn’t worry about it. Like I said, it will maintain full contact with no problem.
