No, that's a misunderstanding many managers have.
TE doesn't work additively :
Meaning ok I have better quality + good formation + tactics + condition + morale + win bonus + training bonus + watching + support ...so I have to win.
The game engine choosing randomly to ignore or to give some more gravity to specific factors in every game.
In your case, the game engine ignored the attacking mentality, ball possession and bonus but rewarded you when you changed tactics.
You could change to all the wrong tactics at that time but it just recognized your coaching effort to reverse a bad out coming.
