He that yes. He also said "is it really the same has the bankai has 1000 yrs ago" or something like that.

And we seen via a 1 panel flashback and Jubabach's words that 1000 yrs ago when Yama would touch something with the blade of his sword fire would come out.

But current day there was no fire just touch and nothing.
