What do you all mean with countering the orders?

[Kto]

Sub a player who has got a yellow card, and count up how many times the sub has got a yellow card later - I've lost count, but by doing so I've prevented my side going down to 10 men

I almost always sub the yellowed player, thats sort of a rule for me, just against headache.

Thats all interesting stuff, thanks to all of you, but can one answer the main primitive question of the thread - what does order countering mean?

We can discuss what else is important, but I have read a plenty of times 'countering the orders' in sentences like 'you must not only counter the formation but also the orders' or 'after I figured out his orders I knew what to do? Some can say there is no order countering , it depends also on abc and xyz etcetc. So probably I hope for an answer from ORDER MASTERS
