I wonder if it's more or less the same thing. Not discomfort, but just looked odd because he had to put a little more effort into the throw than most shortstops with a stronger arm. I've noticed it every now and then too, but he's so smooth with the glove that it's not even worth complaining about. Yeah, it's not like it's some big secret; I've seen it brought up plenty of times that he technically doesn't have as strong an arm as you want or hope from a SS, but it's not like it's got a noodle out there or anything.
