Postfix reports SMFIC_MAIL to the Milter, and the libmilter library
then is expected to invoke the xxfi_envfrom application callback.
Postfix then receives SMFIR_ADDHEADER as reply.
Perhaps Postfix and libmilter got out of sync; for example,
multiple email messages were sent over the same connection,
and the SMFIR_ADDHEADER was really a reply for a previous
message.

The logging shows the SMFIC_<MUMBLE> constants that correspond to
different stages of the SMTP protocol, and the SMFIR_<MUMBLE>
constants that correspond to the responses that Postfix receives
from the libmilter library. The constants are defined in files
under /usr/include/libmilter. There is no formal documentation of
Postfix verbose logging output.
