Yes, and no, the latest version of the manpage says:

/etc/live-persistence.binds
This optional file (which resides in the rootfs system, not in the live media)
is used as a list of directories which not need be persistent: ie. their
content does not need to survive reboots when using the persistence features.
This saves expensive writes and speeds up operations on volatile data such as
web caches and temporary files (like e.g. /tmp and .mozilla) which are
regenerated each time. This is achieved by bind mounting each listed directory
with a tmpfs on the original path.
----- . ------
And there is an example under /usr/share/doc/live-initramfs/example directory:
----- . ------
# /etc/live-persistence.binds example
#
# If this file is present in the proper path, each uncommented not empty line
# will be treated as a directory which should not be made persistent and
# which it's content should be volatile.
#
# This is achieved by bind mounting on it a tmpfs clone of the directory
# specified
# Exclude some standard temporary paths
/tmp
/var/log
/var/cache
# Firefox profiles are not always useful to remember
/root/.mozilla
