Why would a track bike have bottle bosses?
Take a look:

Aside from the obvious re-paint, rear bridge drilled for a brake, and dodgy looking decals, this is represented as a track frame. Yet, it has two sets of water bottle bosses.
Could it be that someone changed the rear dropouts, added a non-drilled fork, and covered this up with a re-paint?
