The calling sequence for this command is slightly convoluted, but it turns out that help.el calls basically (describe-buffer-bindings buffer nil nil) which is a C function (but why?) which inserts all the C-n next-line C-o open-line C-H-w ?? stuff, which is then post-processed to add the xref links. So at the point where the xref is added, then there's no feasible way to determine what the ?? referred to, really, without redoing the work the C function had already done... I think.
