No, that's basically flat tree - a ::part(), selecting an element in the shadow, would see shadow ancestors before it escapes back into the light tree and starts seeing light ancestors.
Anders is talking about something more akin to the tree-scoped names rule, where the tree scope of the @container rule affects what container elements are visible to it. A `@container { ::part() {...} }`, since it appears in the light tree's styles, will skip container elements automatically until it's back in the tree scope it was defined in, at which point it can see all ancestor scopes as well.
I think that makes sense?
