Yep, the outer ring is non-relightable and rely on the launch ring to light them. That said, part of the benefit of having so many engines is that you can tolerate a couple of failures. Similarly to how F9 is able to make orbit with an engine out. Still, agreed that they'll probably opt for one more water landing test first. Especially since the current license allows for multiple launches of this profile if the booster trajectory is fine.
