For me, the definition is right.

[1]:

The subject field identifies the entity associated with the public
   key stored in the subject public key field.  The subject name MAY be
   carried in the subject field and/or the subjectAltName extension.  If
   the subject is a CA (e.g., the basic constraints extension, as
   discussed in Section 4.2.1.9, is present and the value of cA is
   TRUE), then the subject field MUST be populated with a non-empty
   distinguished name matching the contents of the issuer field (Section
   4.1.2.4) in all certificates issued by the subject CA.  If the
   subject is a CRL issuer (e.g., the key usage extension, as discussed
   in Section 4.2.1.3, is present and the value of cRLSign is TRUE),
   then the subject field MUST be populated with a non-empty
   distinguished name matching the contents of the issuer field (Section
   5.1.2.3) in all CRLs issued by the subject CRL issuer.  If subject
   naming information is present only in the subjectAltName extension
   (e.g., a key bound only to an email address or URI), then the subject
   name MUST be an empty sequence and the subjectAltName extension MUST
   be critical.
