Timings aren't a thing that allow one chain and then pass. You stay at a timing until everything the players want to do at it is done. Now, of course, you can't Shield and THEN use his ability, because the attack is then no longer happening. But you can use his skill first, and since it doesn't take up your Counter, you can then cast a Dragon Shield.

This is even directly stated in the Japanese Q&A for H-BT03.
