As far as I know. They just loose the sexing trait. Hopefully someone with more experience will chime in. I have my first Golden Sex-link in the grow-out tractor, she is 8.5 weeks old.
They will be Golden Comets, but will not have the ability to sex them according to down color. That only works with the original generation. Don't quite know if this was the answer you were looking for, but it is how I read it.
