As Gordan noted that we are seeing practically opposite hemispheres, one of the first things to cross my mind was "In that case then where would Cassini have been in the Hubble shot?" After all they should be in fairly close alignment with Cassini behind Titan as viewed from the Earth. However a quick go with Celestia shows that space is big and they are not that aligned closely enough. If anyone else was wondering here is a Celestia screenshot:

Take note of the FOV size in your simulation - the entire screen is a shade under 2.5 arc minutes. In other words, the line of sight difference from a completely 180 deg angle is far less than one degree. I'd call that a pretty good alignment!

Scratch that, it doesn't work that way.
