I took the chance and the TSO said the line served both purposes. Maybe it's a new-ish thing.

One thing to note - now that they have started flying mainline 737s out of there, the security lines have gotten longer and the terminal quite crowded. I could see them wanting this if they have a late arriving crewmember.
