This looks like an official account. According to this explanation, the safe call was due to the ball getting knocked free and not the initial slide/tag. (Not sure why its not embedding but the link is an explanation of the replay decision with a reply of the play in question).
Really interesting rule. Obviously Bellinger didn't intentionally knock the ball away but he was clearly tagged and then transferring to his throwing hand, presumably because Morel is still a live runner on base. But at the same time, Bellinger was completing the process of his slide so I can kind of see why the decision makes sense.
Either way, I'm happy with how it was interpreted.
