Looking at the box-ed segment, it seems like each A[i,j] is dependent on all 4 cells around it : A[i, j-1], A[i-1, j], A[i, j+1], A[i+1, j]. So how is it that we claimed that each cell is dependent only on the ones above it and before it?

Edit: My bad, my question is answered in the comments of the next slide.
