I have implemented a more sophisticated algorithm by now:

  def is_global(overlay_location):
      name = overlay_name(overlay_location)
      return overlay_location.startswith(layman_storage_path) \
          and same_repository(
              available_installed_overlay_dict[name],
              global_overlay_dict[name])

The dictonaries in the last two lines are maps from name to url:
- available_installed_overlay = from %(local_list)s
- global_overlay_dict         = from layman-global.txt

Please let me know what you think about that approach.
To check it out live grab the two python files from
http://git.goodpoint.de/?p=smolt-gentoo.git;a=tree;f=client/distros/gentoo;hb=refs/heads/gentoo
and run

  $ python gentoo.py | fgrep 'OVERLAYS'

For my current setup it prints

  NUMBER_OF_PRIVATE_OVERLAYS = 2
  NUMBER_OF_PUBLIC_OVERLAYS = 7
  OVERLAYS = ['toolchain', 'rbu', 'sunrise', 'zugaina',
    'berkano', 'python-testing', 'python-experimental']
