There is no reason to believe that the code would generate all the unique combinations first.

Yes. Since the code generates solutions in numerically sorted order, there's no reason to believe that none of the reflections could come early.

and search for any occurrence of those numbers in a horizontal row (" 1 12 13 8").

Yep. That's it exactly.
