I must have seen wrong and he had then probably 2 spoils at the beginning of his turn, but still, how is it possible then that, right in the middle of his turn, after attacking, he could once again turn spoils in and once again conquer territories?

Hello,
in a speed-game with 4 guys, someone had 5 spoils. He didn't hand them in tough, but deployed his troops and conquered some regions, eliminating a player. He then played 6 spoils, 2 times 3, and conquerd some regions again. To see, this is the game number: 6934438. I don't know how to explain ...
