I do not see how your example contradicts sections
12.5.1 (link semantics) or 12.5.2 (dead path elimination)?
I think your example is strange but not pathological.
Let us pretend the programmer does not like fault handlers
and structured the process as a graph with one end activity:
Third. In turn, the programmer wants activity "Third" to
be a sentinel or assert of sorts, executing only if activity
"Second" failed. If my understanding is correct, if "Second"
executes and sets "secondToThird"'s transitionCode to true,
Third's joinCondition will evaluate to false, not run, and
the process is finished: after all nothing bad happened ....
and this is what the programmer intended.
Cheers,
Andrew
