Of course it is not a scientific poll. It's 23 people.
You asked: "Undecided swing state voters." How do you determine the accuracy of that claim? How do you determine the meaningfulness of that group?"
I would say that about any poll respondents and any participant in a focus group. Here, the participants had been polled before and were undecided when polled. And the WP knows who they are, where they live, their professions, etc.
Their discussions about individual issues that came up during the debate certainly have as much validity as speaking to 23 undecided voters at their doors or on the phone. As the WP put it: "Our group is too small to capture how uncommitted swing-state voters feel overall, but it still offers an intimate window into how uncommitted voters, who will be some of the most important voters this election, are thinking and feeling about the debate in real time."
