I'm pretty sure he's talking about something like an Itsuu, 4throw or 3C[m] opener where you do 6C(1) 4kote Hatsu, but he's got his moves in a completely impossible order (I don't see how or why you would do hatsu 6C(1).
In any event, anything involving Itsuu and Riichi A requires a fair bit of practice, and there are dozens of ways to consolidate doing them. If you clarify the exact combo you're trying to do I can probably help.
