1. I don’t remember if it was stated in the Shlaer-Mellor or Mellor-Balcer books or if I read/heard it elsewhere, but Moore and Mealy are mathematically equivalent. It really doesn’t matter which one you use. I agree with Lahman’s preference, but it really doesn’t matter.
2. I didn’t see anything in the video that said setting the mode attribute was causing a transition in the instance based SM. If it was the intended effect, then you would need to send a signal. The video is just showing simple OAL usage in a transition.
