Because it gives the clones a lot of chakra and Naruto can chose the amount like when he fought Kaguya, and if he is fighting a Rinnegan user he will have to go RSM or use Kurama avatar clones, and based on Boruto Nardo the movie a Rinnegan user like momo can absorb those clones, so if Naruto used those clones on Sasuke he would absorb them via preta path and gain their chakra and acheive Naruto's RSM and maybe he could use Kurama avatar.
