I give the english sentence precedence over the label for a specific row in a table.
For the example treated by that table, it does not change the numbers. That said, I suppose it would be worth talking with Steve Jost about this issue. He likely has references worth reading that lead him to write that sentence, and he might even like to hear someone having noticed the conflict in his treatment of that topic.
