Does with-selected-window set current buffer?

I am trying to understand if with-selected-window sets current buffer to
the selected window.

with-selected-window calls select-window. The doc string for
select-window makes me a bit confused. At the end of it is a notion that
the command loop selects the buffer of selected window.

Does that mean that select-window does not select that window? Or what
is the comment about?

The reason I am asking is that I have recently seen some cases where I
use with-selected-window in a timer and it looks to me like the code has
been carried out in the wrong buffer. I am not sure yet what is
happening though.

Well, the current buffer can't be a window object.  I think you meant to
ask if with-selected-window sets the current buffer to the buffer
displayed in the specified window.  As far as I can tell, it does.

Not always.  Sadly, it does it in most cases, so it's easy to be mislead
into thinking that it does.

Thanks. Then it would be very good if the doc string reflected this.
