When the outer `insert' is executed, the selected window is not the one
displaying *scratch* but the one displaying *Messages*, so the window's
point is not affected by `insert'.
You're just seeing the effect of the fact that each buffer has N+1
different `point's, where N is the number of windows displaying this buffer.
