You are correct. The makers decided to cut out a 2 second clip of the cart driver smiling to make it open ended and let the audience decide what happened. The original had a clip, which is still obscure as it only shows the mouth, hair and just a bit of the eyes. (if you don't believe me just search the internet for the original ending)
