WebE subtracts 5 times row 1 from row 2. Then F subtracts 4 times the new row 2 (changed by row 1) from row 3. In this order FE, row 3 feels an effect from row 1. In the order E−1F −1, that effect does not happen. First F adds 4 times row 2 to row 3. After that, E−1 adds 5 times row 1 to row 2. There is no 20, because row 3 doesn’t change ...
