aria-selected state for grid rows

I'm curious how (or if) it is imagined that states and properties applied to rows in grids cascade to their child cells.  For example: Can cells inherit the "aria-selected" state or "aria-haspopup" property from their parent rows and then communicate that state to AT when the cells are focused?  This would make sense considering the recommended keyboard access for grids is to move focus through the cells with the arrow keys.  But if this is the idea, I haven't found this to work in practice.  So, I figured I would step back and validate my interpretation of the ARIA Spec.
