The point of Dot is that it is a tensor operation and that it sometimes corresponds to matrix multiplication. In terms of tensor indices, Dot contracts the right-most index of the first entry with the left-most index of the second. Two matrices A and B which satisfy AB=BA (1) under matrix multiplication are said to be commuting. In general, matrix multiplication is not commutative. Furthermore, in general there is no matrix inverse A^ (-1) even when A!=0. Finally, AB can be zero even without A=0 or B=0.
