Setting resize-mini-windows to nil means that resize_mini_window() will return immediately after setting the start of display to its default value (namely BEGV). Setting max-mini-window-height to 1 does not have that effect, resize_mini_window() computes the height that would be necessary to display the content of the minibuffer, compares it to the height that is actually available, and uses that height to calculate the start of display, by moving backward from the height that would be necessary (which does nothing in this case, given that height == unit).
