Section 3.4 says:

  7.  SYN-SENT    <-- <SEQ=400><ACK=101><CTL=SYN,ACK>  <-- SYN-RECEIVED

  8.  ESTABLISHED --> <SEQ=101><ACK=401><CTL=ACK>      --> ESTABLISHED

                    Recovery from Old Duplicate SYN

                               Figure 9.

It should say:

  7.  ESTABLISHED <-- <SEQ=400><ACK=101><CTL=SYN,ACK>  <-- SYN-RECEIVED

  8.  ESTABLISHED --> <SEQ=101><ACK=401><CTL=ACK>      --> ESTABLISHED

                    Recovery from Old Duplicate SYN

                               Figure 9.

Notes:

To align with figure 7 in the same section, after TCP A get the SYN+ACK from TCP B, TCP A should enter ESTABLISHED state instead stay in SYN-SENT state.
