Perhaps with your configuration. And this is probably also true when
the full resolver is not involved. But this is not the general case.
By default, the apt preferences are such that unstable is preferred
over experimental. But as explained in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=795228
this is not the case with aptitude's resolver:
