Funny you mention this. I am working with a new partner tomorrow and as a joke, I told him I was brushing up on all these situations in case we had a multiple foul. I asked him if one was intentional, would they get the ball OOB after the 4 FT's and count the basket? His reply was that if I call a multiple foul, I'll be handling the situatioin myselft and walking home (even though I'm driving).
There is a definition of a multiple foul, however, it is a ficticous creature, kind of like the Lochness Monster. Although, if you read enough of the threads here, I believe someone actually saw one once.
