Did you mean "be"?

This description needs to be clarified.  Something like (I hope I
understand the full effect of the command):

 These commands switch to a window in the direction of the arrow, like
 @kbd{C-x 4} followed by an arrow key, but they also move the current
 buffer to be displayed in that window.  (The buffer which was
 displayed in that window will be now displayed in the
 previously-selected window, i.e. the two buffers swap their windows.)

AFAICT, if the user does exactly what the tutorial says, he/she will
be in the upper window at this point, so "C-x 4 <UP>" will signal an
error.  Perhaps the text should be modified to cater to both
situations, because it is unknown how many times the user will type
"C-x o".
