Armored (2009)

Why does the movie Armored (2009) have 2 identical English subs on the bluray? They differ by only 1 byte. And I can't see any difference when opened with BDsub2sup.

One standard disc authoring practice is to make all titles across the project to have the same number of audio and subtitle tracks so that audio and subtitle setting commands could be easier to handle. I'm not sure if it's the case here.
