Is this a non sequitur?

Don showcases the writing skills of Pat Lynch:

Four Walton family members are on the list of Forbes billionaires inside the Top 25 wealthiest people on earth. This does not include Alice Walton, who lives in Texas.

So either Alice is not among the wealthiest, or Texas is not on earth. You make the call.
