That was probably Kishimoto completely forgetting that chakra cloaks act as a shield. Orochimaru's Sword of Kusanagi (can cut through mostly anything) could not pierce Naruto's Four Tailed V2 form, while the one Shin used (Sasuke's Sword of Kusanagi) was regular steel.

Unless you want to imply Hokage Naruto's SPSM enhanced Kurama cloak is weaker than his old rage induced Four Tailed V2 form.

So by this logic, Kishimoto just forgot, like how he forgot to give Boruto the Byakugan.
