It's all documented. A quick grep of spec.txt for "md5" found this
extract from section 11.6 in about 10 seconds:

    .   "{md5}" computes the MD5 digest of the first string, and expresses
        this as printable characters to compare with the remainder of the    
        second string. If the length of the comparison string is 24, Exim    
        assumes that it is base64 encoded (as in the above example). If the
        length is 32, Exim assumes that it is a hexadecimal encoding of the
        MD5 digest. If the length not 24 or 32, the comparison fails.


So the answer to your final question is "yes".
