They are, in fact, set in filter_begin. From the man page (my emphasis):
GLOBAL VARIABLES SET BY MIMEDEFANG.PL
The following global variables are set by mimedefang.pl and are avail-
able for use in your filter. ALL OF THESE VARIABLES ARE ALWAYS AVAIL-
ABLE 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.

Because it's automatically called prior to filter_begin, so calling it
again is redundant.
