I consider these one terminal, they do not require passing through additional security. SEA is my home airport and I'm well aware of the N and S concourses. It's often just as fast to get to the S concourse as it is to the very end of the A gates in my experience.

Seattle-Tacoma International Airport (SEA) consists of one terminal with 6 gates. On the south end A, B and S gates and on the north end D, C and N gates, these can all be accessed with our North and South train systems to get from one side of the terminal to the other quickly
