I don't understand how 'force-same-window' can be non-nil if there is
a condition "unless switch-to-buffer-obey-display-actions" in the
interactive spec.  But if some code calls 'switch-to-buffer'
non-interactively with non-nil 'force-same-window', should it
signal an error when 'pop-to-buffer-same-window' displays the buffer
in another window?
