I agree with your change, but I don't think it goes far enough.  Here's
what pop-to-buffer's doc string says:

| If optional second arg OTHER-WINDOW is non-nil, insist on finding another
| window even if BUFFER is already visible in the selected window.

To me, that means that no calls to (pop-to-buffer BUFFER t ...) should
obey same-window-buffer-names or -regexps, not just those in
switch-to-buffer-other-window and -frame.  And so I think the job of
temporarily binding same-window-buffer-names and -regexps should be done
in pop-to-buffer:

(let ((same-window-buffer-names (if other-window
				    nil
				  same-window-buffer-names))
       (same-window-regexps (if other-window
			       nil
			     same-window-regexps)))
   ...)

Unfortunately, pop-to-buffer is implemented in C and I don't know how to
write that fragment in C.
