The same place the data in any ArrayList comes from: it comes from whatever source you as a developer use to fill it. There is no "backing by a database" involved in the standard Model implementations in RDF4J - they are just passive in-memory data structures.
Perhaps Halyard is using some custom implementation of the Model interface? If so that could be causing the confusion here.

PS I told a small lie I just realized: there is one implementation of the Model API that is backed by a database in RDF4J: the SailModel class. But it's for internal use only (mainly because it's not a recommended abstraction pattern, and prone to memory leaks if not used correctly) and not intended for use by third parties.
