Well I know I posted on their Facebook page about the shirt, and I think others did too, plus, unlike a head, it's really not complicated to add an extra shirt, they might have figured people wouldn't care and when they saw they did threw it in. It probably cost nothing to do, plus it was just a matter of using black fabric for the same pattern as the gray. A second head is something else. Plus, people aren't as into the Sarah so they're not going to push for as much accurracy or whatever on her. People are far more psyched for T-800 and T-1000, Sarah only really caters to the very die hard T2 fan, or people looking to get her for parts and those people won't care about what she doesn't come with.
