The string being matched in the explanation at that link is 'abcbd',
not 'abcdb'. The 'a' in the pattern matches the 'a' in the string, the
'[bcd]*' in the pattern matches the 'bc' in the string (with a repeat
count of 2), and finally the 'b' in the pattern matches the 'b'
following that in the string.
