I consider a.m. as a spy who's taking a peek in game's secret calculations.
Also a program that check the current stats of the match and (randomly) pick some of the weak points of those it can spot.
So Talisman, in the beginning he spotted that maybe we have fewer shots on target or much less tackling from our oppo and suggested the high pressing.

After some re-calculations of the game flow, he spotted some of the weak points again.
(Some times it's more than one, some times maybe there isn't, so he speaks generally - Let's beat those amateurs , for example).
One of them was that our condition is too low for that moment of the game and suggested to remove that.
A.m. hasn't a general plan in his mind (like we do), just suggesting randomly advice.
