I'd say this is a generally misleading statement, but if you like it is right in some context. In particular, one could argue that it is true for clustered indexes (e.g. in SQL Server or MySQL/InnoDB). In that case the table is actually in an ordered fashion and happens to be identical to the leaf-node-level of the index. However, if you argue that this level doesn't belong to the index but is just the payload, the level above the leaf nodes is as they say: it has one pointer per page.
