Correct. It ignores the label portion of the ref value per

RFC 2255, Section 3:
Note that any URL-illegal characters (e.g., spaces), URL special
characters (as defined in section 2.2 of RFC 1738) and the reserved
character '?' (ASCII 63) occurring inside a dn, filter, or other
element of an LDAP URL MUST be escaped using the % method described
in RFC 1738 . If a comma character ',' occurs inside an extension
value, the character MUST also be escaped using the % method.
as shown in examples provided in Section 6.
If this, in your opinion, isn't clear enough, I suggest you raise
an issue with the IETF LDAPbis WG which is chartered to revise
