Splitting worlds could mean creating new worlds or dimension just like the power of Kaguya's expansive TSB. A dimension within a dimension.

For comparison from other anime such as Inuyasha, Kinshiki's technique could be something like Meidō Zangetsuha of Inuyasha's Black Tessaiga kinda like Backlash Wave.
