Katen Kyōkotsu and Sōgyo no Kotowari manifest them self as 2 separate spirits. Hisagi's zanpakuto has only one spirit. For the latest version of Zangetsu it is unknown. As far as I know, they "show" themselves as 2 separate entities, but they're still one spirit, while Ichigo's blades are 2 different spirits ("Hollow" Zangetsu and "Quincy" Zangetsu)

This got me thinking; Will Ichigo use the same stance/pose to release his Bankai, since he now uses two blades. Normally he fully extends his left arm out in front of his body, and brings his right arm in and puts his right hand slight over his left arm In all honesty, I'd assume his Bankai release would have something to do with the holllowed out portion of his bigger blade.
