Despite the spec https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectVersions.html#API_ListObjectVersions_ResponseElements
says that
"When the number of responses exceeds the value of MaxKeys,
NextVersionIdMarker specifies the first object version not returned
 that satisfies the search criteria. Use this value for the
 version-id-marker request parameter in a subsequent request."
 the actual behavior of AWS S3 is returning NextVersionIdMarker as the last returned object version
