Tim; See the description of afn:substr in Help > Reference > Functions
Overview. The index starts a 0 and a negative integer would therefore
be out-of-bounds. The following would do what you want:
SELECT DISTINCT *
WHERE {
?s a ub:Organization .
BIND (xsd:string(?s) AS ?str)
} afn:substr(?str, fn:string-length(?str)-2, fn:string-length(?str))
