C-x 2 in step 3 does _not_ "use" the new window on *Messages*.  Hence
at the time you do C-x 0 in step 5, the most recently used window
(with exception of the one you are about to delete) is the window on
*scratch*.

Using a window means selecting it, see 'window-use-time'. Hence if,
before C-x 0, you first select the window on *Messages* and then
reselect the *Info* window, C-x 0 will select the *Messages* window
instead.
