The "expected result" listed isn't a valid output for get_matching_blocks() which is documented to return "triples are monotonically increasing in i and j".    In your example, the "a" sequence is increasing: 0, 2, 5 but the "b" sequence is not monotonic: 3 0 5.

SequenceMatcher.get_matching_blocks() isn't designed to locate swapped blocks from "abcd" to "cdab".
