Yes!
But as to how it affects it - that gets a little more complicated.
Actual Landing Distances are calculated based on analysis of flight test "Performance Landings" which are flow to a specific set of conditions. In general most normal landings will be less 'performance oriented' than these test landings (which is fine, usually there's runway to spare). The kind of landings you describe fall into that category.
Almost certainly they are requiring a larger 'air distance' than has been assumed in calculating the landing distances. However it's probably that the touchdown speed is actually lower than would be the case for a 'performance landing' - as the plane has spent more time decelerating in the air. Therefore the stopping distance may well be shorter.
I'd expect the overall effect to be that a longer total distance (including the airborne distance) is being used than the manual lists.
