Greg, Per my understanding of the NFPA Manual of Style to require both items as a single criteria would define a multiple levels of safety situation and that is not allowed. I read this to be two separate criterion: In the first it's an exposure if it meets the two conditions-100 sqft larger and within 50 ' of another structure. In the second it is any size, classified as a 3 or 4 hazard and within 50' of another structure. If it's 99 sqft larger, not a 3 or 4 hazard but closer than 50' it's NOT a hazard. If it's 51' away and 100' sqft larger and/or class 3 or 4 it's NOT a hazard. Etc.
