Perhaps he wanted to use the strings as some sort of serial number and
message in one, i.e., something a not-trying-to-be-clever programmer
would implement as a tuple or class.  For example:

    # checking to see if two messages refer to the same event,
    # in which case print the message only once
    if a is b:
        print a
    else:
        print a
        print b
