IIUC you want to change xref--show-pos-in-buf to use 
pop-to-buffer-same-window or switch-to-buffer instead of display-buffer.

Would you like to propose a patch that would still honor the 'action' 
argument (or the values of xref--original-window* directly)?

Also pinging João who wrote that code.
