No, each tube has its own starter and the two tube+starter pairs are wired in series with a single ballast. I understand that this is a common arrangement for tubes shorter than 2 feet in length. The box has obviously been designed to work this way, and it does work fine. I'm just not sure that the ballast is correct, given that it's only rated for 13W and is running two 8W tubes.
