jeff asked:
i understand why there can be isur on top of isur; but why it must be in the order of increasing severity?

The Kollel replies:
The rule according to this Tana is the opposite -- Ein Isur Chal Al Isur, which means that once something is already Asur no new Isurim apply. However, this Rebbi Yosi (in Yevamos) admits that where the new Isur adds something to the existing one, then Isur Chal Al Isur.
