I think this was talked in another post. If I remember correctly, Nasu had said something about that this new power had a meaning (thus we will, supposedly, know more in the future).

This was the statement

4Gamer: The scene in that passageway was one of the scenes that I was thinking about while playing. By the way, Shiki was killing Lore's legs along with the corridor, but does that mean anything? Mr. Nasu: There is a proper meaning. Also, I think everyone has doubts that there is only one route for Arqueid ... but that too.

Shiki killed Roa body along with the corridor but has you can see from the interview he did not go into detail about how Tohno was able to do this but I guess it's a new power that Tohno has

My theory is sense Tohno can see the death of space in the remake which is said in the Tsukihime Material I

Ultimately, it becomes possible to not only see the "lines" and "points" of living and inanimate things, but also the death even of space and existence

he could kill the space and that means he can kill things from range but that just a guess we have to wait for Nasu to give us the answer

Plz bro, don't spoil me
