ACL：default user does not have permission to execute the psync command？

[catpEast]

The comment in redis.conf(redis7.0.15) says that the default user does not have permission to execute the psync command, but it does.

# However this is not enough if you are using Redis ACLs (for Redis version
# 6 or greater), and the default user is not capable of running the PSYNC
# command and/or other commands needed for replication. In this case it's
# better to configure a special user to use with replication, and specify the
# masteruser configuration as such:

# masteruser <username>
#
# When masteruser is specified, the replica will authenticate against its
# master using the new AUTH form: AUTH .
