Your statement does not falsify the quoted statement; both can be true that the ROC would not surrender and that China might inevitably absorb Taiwan. If we want to get really pedantic, no timeline was also stated, so this could also be 50 to 500 years from now.
Obviously, the context the meaning was that there was a cause to effect link between how things were going in China and, especially HK, and the likelihood of a reunification with Taiwan.
So I pointed out that the situation in HK is not really relevant because, even if it had gone perfectly 'well' the ROC would still never had surrendered to the communists. The bottom line is that regime change on the mainland is a necessary condition.
