 Correct, this is a bug, precisely, entering the submachine does not check
 for waiting deferred events.
 This would be solved by adding inside do_entry inside state_machine.hpp:

 handle_defer_helper<library_sm> defer_helper(m_deferred_events_queue);

 before : process_message_queue(this);

 This will have for effect that MSM will process
 ev_async_send_cmd_with_reply(1) when entering, and
 ev_async_send_cmd_with_reply(2) will be the last displayed text.

 But frankly, after seeing this, I'm unsure whether it's a great idea to
 keep deferred events while leaving the submachine, I need to think about

 To check if it solves your problem, I committed this fix in trunk rev.
