Did you try it?  In a default Emacs this won't split anything but either
reuse O or make a new frame.

It is.  But in a default Emacs you still won't get your third window.
You can't beat the system by using ‘pop-to-buffer’ alone.

Which IMHO is no problem per se.  But you probably have to explain
somewhere that ‘xref-find-definitions-other-window’ _by default_ behaves
just like ‘xref-find-definitions’ when leaving *xref* visible.
