AD9957 PROFILE<2:0> and I/O_UPDATE pins

In the AD9957 Datashet on page 10 it is written about PROFILE<2:0> pins: "State changes should be set up to the SYNC_CLK pin."

Do I understand correctly that I need to add the D-flip-flop on these inputs?

Shall I do it on I/O_UPDATE pin as well?

Example circuit I have shown in the picture.
