[strongSwan] tcpdump of ping over ipsec transport

I have two machines, with ipsec configured to encrypt every packet going
between the two (transport esp), with pre-shared key.

When I ping machine A from machine B, and I do 'tcpdump -i <dev> esp ‘  I
dont see ESP packets going bi directional but rather only the replies from
B to A. Is this the expected behavior of tcpdump in that case?
