Best double check your sources Terry.
The source I'm using is the poll itself. It shows where Dabo voted.
The article says this:
It’s important to note that Swinney’s vote in the coaches poll was made with no knowledge of what the final four in the College Football Playoff would be. The coaches poll came out just before Noon ET on Sunday, Dec. 3, before the selection show for the College Football Playoff began.
The link in the article says something completely different.
