The start of that section, called "GLOBAL VARIABLES SET BY MIMEDEFANG.PL",
explicitly says:

   The following global variables are set by mimedefang.pl and are
   available for use in your filter. All of these variables are always
   available to filter_begin, filter, filter_multipart and filter_end.
   In addition, some of them are available in filter_relay, filter_sender
   or filter_recipient. If this is the case, it will be noted below.

I suppose the manpage could be made even clearer by adding the word
"also": this variable is also available in... etc.
