The Fritz PowerBook is compiled from a GM database with the only criterion for
including a game in the book being the playing strength of both players.

The PowerBook doesn't contain *any* preferences to make Fritz prefer or avoid
any kind of opening lines, except of course the statistics from the human
database (win/loss/draw ratio and move frequency as well as ELO performance
which Fritz doesn't use AFAIK). It's basically just a good database, nothing
more and doesn't include any previous Fritz games.
