The workflow examines the five element list split from the first service. For each element, if it contains an 'a' followed by two characters, the second character after the 'a' is included in the output. Thus, for the input ['a','b','abcde','cdef','axy'], only 'abcde' and 'axy' contain a match and so ['c', 'y'] is output.
