Doesn't a personal foul (contact) usually precede a unsportsmanlike foul (non-contact).
Like, a B1 hovering over A1, then A1 saying 'HACK off', then B1 shoving A1, then A1 shoving B2?
It would seem that you could always call the worse foul, the UNS, when there are two 'fouls' by each player, the taunts, then the shoves. But every game I've been involved in, when these actions occur, and it gets physical, the lesser of the 2 fouls is called - the PF on each player, then offsetting.
Why?
