They maybe the same person.. in the past we've seen the manga give us a different spelling of the person's name so it maybe the name issue. Urd Geales was once spelt differently but we didn't assume that they were different people, so there is chance that they maybe the same person.

Shinoa also felt the sword stab into her heart and Guren was also talking about what Shikama-doji tells her..

considering all this they must be the same person.
