It's not very surprising they'd be distant relatives, as a matter of odds.
Taiwan is a small place and Taiwanese Han people came from a relatively non-diverse group of immigrants (e.g. largely Hokkien). For these two to have got a good education and risen to the top like this as immigrants to the US, likelier than not they were from educated or rich families.
If you filter for Taiwanese families educated or rich during the years they were born, the scope would probably have been somewhat small and covered an even smaller range of bloodlines, possibly even all somewhat related to a handful of historical clans.
The degree of separation between people like them from a small geographical region tends to be fairly small in general.
