Once you've applied the CARP patch, you can set the maxupd for the
pfsync interface, but you are correct that the man page makes no
mention of that. I suspect it's merely an oversight, as the working
code is more important than the minor documentation required. People
playing with unofficially released code should be used to minimal docs
and reading the source to find out what really goes on.

All the PF and CARP docs suggest a dedicated interface for pfsync,
mostly due to security issues. The most common implementation I would
assume is a pair of firewalls each with 3 interfaces (internal,
external, and sync connected via a xover cable).
