WAI-ARIA 1.1: grid and table

A grid as defined is "An interactive control which contains cells of tabular data arranged in rows and columns, like a table". 
Therefore, it has   a data-table semantic and not semantic of role=none / presentation.
So, does "Grids do not necessarily imply presentation" mean that grids do not imply mere presentational content like a layout table. They _always_ describe relationship.  

Table: Need to clarify or emphasize that this always has a semantic of a data table. 
Because, when one explicitly sets role=table, one cannot set role=none/presentation.  
This is distinct from a native HTML table that can have role=none/presentation.
