A few comments in the bug database give a hint why this is conditional (http://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14588):

(1) "resources are only handled in the Xt case" (comment #1) (2) "Still no explanation as to why Xt is not used, and this should be conditional on that case." (comment #3)

Now that GUI libraries typically don't rely on Xt any more (e.g., Gtk), but WM_CLASS (and possibly other resources) are still used by window managers, it arguably makes sense for the X11 driver to always set this property.
