Like you I also heard back then the US carriers were not flag carriers so did not have this problem. But SQ was the flag carrier for Singapore, right? I do not recall them every having a different name on their planes and they had a ton of flights to Taiwan back then. I do not recall exactly when they started Mainland China service, maybe by that time the rule was not being enforced. I would have thought it was before mid 2000s though.
