For the first matrix $A, L$ keeps the 3 zeros at the start of rows. But $U$ may not have the upper zero where $A_{24} = 0 .$ For the second matrix $B, L$ keeps the bottom left zero at the start of row 4. $U$ keeps the upper right zero at the start of column 4. One zero in $A$ and two zeros in $B$ are filled in.
