Virtual Private Wired Service (VPWS) also known as P2P xconnects do *not* perform MAC address learning at the AC nor PW levels, is a P2P connection, so the idea is just to 'flood' the data that is received from the AC towards the PW and from the PW towards the AC.
Note that this also applies to EVPN-VPWS.
If you require MAC address learning at the AC/PW levels, use a bridge-domain and configure the PW over this. After the configuration is done, you can use the following command to check the MAC addresses learned under the particular bridge-group / bridge-domain:
show l2vpn forwarding bridge-domain <bridge_group:bridge-domain> mac-address location <LOCATION>
