Does the same approach apply with the "Glass" portion being sss material and the "Liquid portion being a standard dielectric. Say your cup was translucent plastic and inside was water basically. Hope that makes sense.
All bets are off with SSS (I doubt it works the same) ... but I have not really studied this to the same lengths as the regular liquid+glass.
[speculation]
Somehow I don't think the SSS calculation stops unless it encounters a corresponding exit surface. This means that once a ray enters an SSS volume it may keep producing SSS even if it encounters a sub-object (enclosed liquid) ... (as if it turns ON/OFF only when it encounters opposing normals of the same surface).
