The bit that neeeds emphasising is
...give you a testing system.
That is what the second entry in sources.list does.
It doesn't matter what the other line is, the user is working
with a testing system. That is where the packages come from.
Having said that, the option to pull in packages from stable
as needed is moot, apart from security updates or absence on
testing. It looks like cargo cult.
