In this specific case, it was probably further from the strike zone than the pitcher wanted. That said, pitchers throw balls often to see if hitters will swing at them, and some hitters are more apt to swing at bad pitches (and therefore pitchers exploit this).

Pitches at the bottom of the strikezone, or pitches that are low and drop below the strikezone (that would be called balls) are generally hard to hit, so a lot of pitchers throw sinking pitches there hoping to either get a very borderline strike or a swing and miss.
