This is very important, and actually very strange. I constantly run in to problems with this when grading. Let's say I have a close-up of an eye and I just want to work with the iris, there is no way for me to first mask out the iris and then exclude the pupil with another mask. I know, you can duplicate the clip and make another mask, but that's a workaround (and not a good one). If you want Premiere to be a serious contender for colorists and grading, you have to fix this, just adding blending modes like Franklin here suggests can't be that hard?
