This is as it always works:

  Acquisition provides for only one level of "backtracking" -- for
  the currently looked up name. Names which have been looked up
  successfully are not retried.

In your case:

  "widgets" has been successfully looked up in "plonecollectorng".
  After that "foobar" is lookup up in this "widgets" and its
  acquisition context. The content of "archetypes/widgets" does not
  belong to "plonecollectorng/widgets"' acquisition context.
