Chaff is to put clutter on a radar, flares are to distract heat-seeking missiles. Coupling it doesn't do anything unless there's somehow a missile that has both an IR and radar guidance(don't think this exists).
I mean there's some missiles that can be equipped with either type, such as the French mica and the Russian r27 but it's a swap not a both simultaneously, so unless there's some surface to air missile that does it than idk. Modern radar missiles can use the internal radar and the airplane radar for tracking, but I don't think that's what you meant.
so my source for the both types of missile tracking thing turned out to be a Quora ChatGPT answer lol, but i think they still train people to use both flares and chaff because you might be targeted by multiple hostiles (like several SAM batteries or multiple jets or a single jet launching multiple missiles) and most planes carry enough of both anyway

AFAIK plenty of modern 'fire and forget' missiles use both

You still need to use both, cause you don’t wanna find out you deployed the wrong one
