Hi Fabian, in the current snapshot (i.e. 3.3 not 3.2), all SPARQL queries are translated into native SQL for the underlying database. This means the order of results depends on the database system. Personally, I would not make any such assumptions, because it could also happen that someone modifies the data while paging.
