I'm still not entirely convinced by this change, as it only focusses on the difference in storage. How about this instead:

    [[def_pseudoref]]pseudoref::
        A name that can be used like a <<def_ref,ref>> to refer to an
        <<def_object,object>>, but that has different semantics: it can
        record more than one object ID and may carry additional metadata.
        In contrast to root refs, pseudorefs are therefore not stored or
        handled by the ref backend. They can be passed to commands like
        linkgit:git-log[1] or linkgit:git-diff[1], but cannot be written
        by linkgit:git-update-ref[1] or listed by
        linkgit:git-for-each-ref[1].
