I'm new at this too, but AFAICS these are both exact matches: they have
the same matching lexemes at the same positions, so the basic rank
calculation is going to come out exactly the same. Normalization option
32 doesn't help (as the manual notes, it's purely cosmetic). So it's
random chance which one comes out first.
What I think you might want is one of the other normalization options,
so that shorter documents are preferred. Either 1, 2, 8, or 16 would
do fine for this simple example --- which one you want depends on just
how heavily you want to favor shorter documents.
