I think that is talking about something different, namely the difference
between linkend and href properties. linkend points to a tag in the
current document, and AFAIK it behaves the same in <link> or <xref>.
href is used for external links.
The author of the cited page may believe that <link linkend=...> is bad
style, but he doesn't say that in so many words, and even if he did
I'm not sure I would agree.
