On the Subject of The Maroon Button

Hold on, isn’t this The Red Button? Why are there flags?

The screen cycles through five different flags. One of the flags, A, is from a different continent from the rest. Sort the four other flags based on their latitudes in the table below and in which direction the screen is cycling. If the screen is cycling from left to right, order them from north to south. If the screen is cycling from right to left, order them from south to north. Press the button when the flags are highlighted in this order. Press A last, no matter the latitude. However, if the last digit of the serial number is even, press A first.
