In theory yes, but in practical application not always true. Smaller flies are often sparsely tied with slim profiles and will not always be "wash ahead" of the "heavier" fly.
Furthermore, you can also mend your rig to ensure that the "control" or bigger fly is ahead (ie downstream) of the smaller "point" fly and ensure that you eradicate all slack from the rig so that when a fish touches the fly the indicator responds without the "delay" you are refering to.
Rig also works well on clanwilliam yellows, my best yellow to date on an indicator rig.
