You're right about the flow control.  The immediate commands have the same
flow control problem, because in their case, the CmdSN is not advanced.  From
1.2.2.1:

"Commands meant for immediate delivery are marked as such through an
immediate delivery flag. They carry the same CmdSN as that which
would have been given to a non-immediate command but the CmdSN is not
advanced for immediate commands."
