Yes. Same with outgoing locally generated packets.

This is a misuse of the name PREROUTING, to make things easier to
understand. PREROUTING is only an iptables built-in chain for some
tables, and of course connection tracking does not occur in any iptables
chain, as it is independent from iptables. Connection tracking of
incoming packets is called from the NF_IP_PRE_ROUTING hook (see
http://www.netfilter.org/documentation/HOWTO/netfilter-hacking-HOWTO-3.html),
which is the same hook the PREROUTING chains of the various tables are
called from.
