> When inside a form that temporarily changes the current buffer, such
> as "with-temp-buffer", running "execute-kbd-macro" appears to switch

> current command started executing.

'execute-kbd-macro' calls command_loop_1 which sets the current buffer
to the buffer shown in the selected window.

> For example:
>
> (with-temp-buffer
>    (list
>     ;; Returns the temp buffer
>     (current-buffer)
>     (execute-kbd-macro "hello")
>     ;; Returns the buffer that was current when evaluation began
>     (current-buffer)))

Try with

(with-temp-buffer
  (let ((restore (window-buffer))
	temp)
    (setq temp (current-buffer))
    (set-window-buffer (selected-window) temp)
    (execute-kbd-macro "hello")
    (set-window-buffer (selected-window) restore)
    (list temp (current-buffer))))
