PSSM11 — Clarification needed for abortion in Test Behavior 003-A

Test Behavior 003-A describes a scenario, where the doActivity is aborted. There are no alternative traces specified, only the one, where the doActivity is aborted after printing S1(doActivityPartI) and waiting for the Continue signal.

Why is there no alternative trace listed, where the doActivity is aborted before executing the printing of S1(doActivityPartI)? From the current test it seems that the doActivity can be aborted only when it is waiting for a signal. However, Test Event 017-B and Terminate 002​ explicitly lists traces where the doActivity is aborted before printing anything or completing its initial first RTC step.

The Received event occurrence part lists "AnotherSignal – received when in configuration S1". From this, it seems to me that AnotherSignal can be processed any time and S1 can be exited before executing any part of the doActivity.

Moreover:
1) It would be helpful to clarify abortion e.g. in 8.5.5 StateActivation exit. In which phases of its execution can the doActivity aborted? At the boundaries of RTC steps? Or even inside an RTC step?
2) A possible test case to showcase these questions could be the following. One simple state with a doActivity, entering the state is triggered by Start, exiting is triggered by Continue. The doActivity has two WriteStructuralFeatureAction, that writes 1 and 2 to an integer value owned by the statemachine, which is initialy 0 (there is neither timing or waiting in the doActivity). Received events are Start, Continue. List of traces could show, whether the doActivity can be aborted in such ways, that in the end the integer is 0, 1 or 2.
