    IMHO the answer is wrong.
    Each connection creates its own session (especially when every new connection uses a different SOURCE PORT).

    Below the command output from SRX3400 (the scenario given in question was replicated).
    You can see two sessions: first served by FPC6, the second by FPC7
    root@FW-1> show security flow session destination-port 23 destination-prefix 192.168.200.1

    Flow Sessions on FPC6 PIC0:

    Session ID: 120468562, Policy name: P4/22, State: Active, Timeout: 1796, Valid
    In: 192.168.1.1/48783 –> 192.168.200.1/23;tcp, If: reth2.10, Pkts: 42, Bytes: 4374
    Out: 192.168.200.1/22 –> 192.168.1.1/48783;tcp, If: reth0.200, Pkts: 34, Bytes: 4857
    Total sessions: 1

    Flow Sessions on FPC7 PIC0:

    Session ID: 140870820, Policy name: P4/22, State: Active, Timeout: 1798, Valid
    In: 192.168.1.1/48781 –> 192.168.200.1/23;tcp, If: reth2.10, Pkts: 76, Bytes: 5998
    Out: 192.168.200.1/23 –> 192.168.1.1/48781;tcp, If: reth0.200, Pkts: 122, Bytes: 13561
    Total sessions: 1
