Agreed, you are right. The break to L2 does require a response whereas the break L2->None does not. The break L2->None is to inform the client so it arrives at the same consistent state.

Shouldn't this read "Break level2 to none", or what do you exactly mean by "is async"? My understanding of "async" is to not require a response. The break to L2 does require one, right? It's the break L2->None that does not.
