Other type of movement stopping:
Say you move a large army from country A to enemy country B.
Country B sends one unit to country A in the same turn.
Owner of country B executes his turn BEFORE owner of country A.
The result is that the units from country A will never move to country B and there will be a fight in country A, not country B.

And it's always been like this :p
