There are different kinds of handball fouls.
1. Non deliberate handball, most of which are usually insignificant; this one is usually a non-bookable offence.
2. Non deliberate or somewhat deliberate handball that interferes with the general game-play (that is, it is likely to have an effect on the game); this is a bookable offence (yellow card).
3. Deliberate handball that prevents a goal or a clear goal-scoring opportunity; this is considered as a serious foul (red card).
So, during simulation, your player did the 3rd one, while the other player did the 2nd one.
Many of the so called 'trolls' as posted here on this forum are probably not as such; there are logic explanations to many of those.
