You are both correct.  This method grabs the latest version within the
current universe.  Many universes are static, for example the stable
releases, and thus that version is fixed for all time.  Other universes,
such as the development universe, change over time.  The precise policy is
up to the maintainers of the universe.

A motivating example would be the 3.7 stable universe.  If you want to work
with a 3.7-ish set of Squeak code, then you can still download the 3.7u2
image.  That image, released years ago, is a 3.7 image plus a pointer to
the "squeak3.7" stable universe.  That stable universe has 200 packages
that you can still load and work, years after the release was made.
