It is..... and its not the only one either. Christie's 214P triggers what I like to Call a "Kneel Down Stun". The essentially all do the samething but they're are minor differences.
Theres also a Sit Down Guard Break..... I'm sure you are familiar with Nyptengu's 6P+K. Some characters can also Trigger a Back Turned Turn Around sit down stun such as Tina's 8P on Back Turned Foes.
I love sit down stuns....they grant you so much advantage. It's a shame that no particular fighter has alot of them. Try seem uncommon to have
