Yes.  In `switch-to-next-buffer'

(assq buffer (window-prev-buffers window))

provides this information.  `window-next-buffers' is exclusively used
for buffer navigation within a window.  `window-prev-buffers' is used in
other occasions like `quit-window' where I don't care about a window's
next buffers.

Can you elaborate what you mean here?  A new window has neither previous
nor next buffers.
