You're right, so if the puzzle restricts one (arbitrarily) to geodesics as the only valid straight-lined curve (?), it becomes nonsense because the only easterly geodesic is at the equator, and seattle is not at the equator. |

Wrong. There is a perfectly good great circle passing through Seattle and pointing due east at the point where it passes through Seattle. The author showed it to you in the article. That geodesic does not always point due east, but nothing in the article said it had to. The article only said you have to face due east at the start, not that you need to continue facing that way.
