Earlier quoted context omitted.
Maybe the Wikipedia page was just updated, following this post, but it's fairly clear right now. It says fairly clearly in the infobox, "Jensen Huang (表舅 or first cousin once removed)"
"once removed" is not clear at all. To me, it reads like nonsense.
1. Your parents' [first] cousins' children are your 'second cousins';
2. Your parents' second cousins' children are your 'third cousins' (and so on);
3. Your parents' [first] cousins are your '[first] cousins once removed';
4. Your parents' second cousins are your 'second cousins once removed' (and so on);
5. Your parents' [first] cousins once removed are your '[first] cousins twice removed' (and so on).
