TBD doesn't do science, so his guesswork is wrong as often as its right, and he gets sloppy with terminology (and facts). If you are going to talk science, you need to be more precise.
His statement was
"Now the way I read that is there was one ancestor in the last ten generations?"
It was wrong because that would mean he acknowledges the possibility of a more recent ancestor, and I'm sure he didn't intend that.
To be clear, the range given by the DNA expert was
"6 to 10" generations, and that outcome depends very much on certain factors. One of those factors is what Warren actually claimed; there have been a very large number of mischaracterizations, untruths, inaccuracies, exaggerations and downright lies told about what she actually claimed, and about when she claimed it.
What Warren actually claimed was what her family lore said, that she descended from both Cherokee and Delaware tribes. If that family lore is accurate then that will be one of the reasons why there is an uncertainty of ± 2 generations - more than one ancestor in different generations buggers up the percentages and widens the generational window.
I would also like to add that TBD's assertion that "Native Americans are
all slamming her for being racist" is a completely false one. Read on...

While some tribal leaders have condemned Sen. Elizabeth Warren for publicizing DNA results confirming her Native American heritage, the principal chief of Delaware's Lenape Indian Tribe said paying tribute to your ancestors isn't a bad thing.
“Someone who is proud of having that native ancestor — no matter what percentage or what degree it is — in my view, is a person I honor," Chief Dennis Coker said, describing some of his own tribe members' reluctance to do the same because they've traditionally been discriminated against."
Coker's views put him at odds with the Cherokee Nation, who this week slammed Warren's DNA test as "inappropriate and wrong." Coker wasn't surprised by their stance, he said.
They've questioned the legitimacy of the Lenape Indian Tribe of Delaware, too, which is recognized by the state but not the federal government.
“The Cherokee view themselves as the Indian identity police," Coker said. "They’re the first ones to call out anybody that they don’t think is legitimate, whether they're legitimate or not."
"Unfortunately for Elizabeth Warren, she claimed a Cherokee connection, and she ruffled some feathers out there.”
