In the scenario given, the crossing TO the Neutral Zone would not count. It does not meet the definition of Crossing. Any scored Boulders would count (including the first one). The Crossing FROM the Neutral Zone would count. The Reach after the Crossing would be a 50-50 at this point--personally I'd say no, others would have valid opinions the other way--depends on your reading of "another" in the manual section discussing auto scoring.
