I don't think so. It is a Bankai technique, I would think his Zanpakutô spirit taught it to him when he achieved Bankai, and as such knew about it. It doesn't make sense since he said Ichigo was "the second one to SEE it". That implies to me that also the first one was another person.

But he did say "the second one to SEE it". That doesn't mean he didn't show it to Ginrei, since he didn't say that he killed the first one who saw it.

Unless I forget some of his dialogue.
