You're absolutely right. This is important. Re-reading the text I realized that the distinction between initiator and acceptor are completely useless. There is no behaviour difference between initiator and acceptor. I will therefore remove those definitions and remove any reference to them in the text. Simul-init will consequently be implicitly supported. Thanks!
