No. The simple DNA procedure does not stop, but it STARTS USING the 
address as described in the following pseudocode in the NA processing.

foreach SDAT_Entry in SDAT_Entry_List
{
   /* Address is operable. Configure on Interface */
}

If an RA arrives later from the SAME ROUTER, which has none of the 
prefixes, the simple DNA host unconfigures the addresses as described in 
the following pseudocode in the RA processing.

foreach SDAT_Entry in SDAT_Entry_List
{
   if (Exists_PIO(RECEIVED_MESSAGE,Get_Prefix(SDAT_Entry)))
   {
      /* Address is operable. Configure on Interface */
      /* Rejoin solicited-node multicast group for address */
   }
   else
   {
      /* If address is configured on interface, remove it */
      /* This could be because of a NA arriving before RA */
   }
}

Thanks
Suresh
