Answer
In the latest version, the Global Filters act on all mail whether local or not.
In previous versions, a distinction was made between filterscript and eomscript where eomscript worked on non-local mail and filterscript worked on only local mail. This meant that global filters did not act on non-local mail. This has now been changed so that global filters work on all mail.
