Many of us will wait at least a week or two after backsweetening before bottling. I typically wait at least a couple weeks after adding potassium sorbate before I backsweeten, too! (I add kmeta after fermentation completes and then every 3 months of aging, then as I am bottling, so it may be done at a different time than when I backsweeten.)
@Rice_Guy has mentioned 9-12 months aging of the unsweetened wine usually is safe for NOT using potassium sorbate before backsweetening because any remaining yeastie beasties should be well and truly dead by then.
