As far as I understand the rules here the second question should have been marked as a duplicate, the answer to the second question posted under the first question?
Answering this with the merits of the second question/answer combination's merits is irrelevant.
Either the policy was ignored or the explanation text needs redaction. If these kinds of decisions are to be repeated, then in the future the dupe-closure text has to include "was now better asked", "has now a better answer"?
