Only difference here was that Kira IMMEDIATELY put up a healing barrier to stop bleeding and helped recovery. Hiyori has been sliced in half for a good 50+ chapters (which equates to 6ish minutes [taking a shounen guess]). Unless Kubo cockslams us into believing Unohana made it incredibly quick to her aide when she was running through the Hueco Mundo path, then she's most likely dead. But ya, Orihime will just fix her right up.
My theory on Bleach.
Aizen is Ichigo's long long lost son/grandchild/great grandchild from the future who happens to have went back into time because the Aizen we know now destroyed the Reiatsu train thingy.
THAT'S RIGHT, KUBO DELIBERATELY ALLOW TIME TRAVEL TO BE POSSIBLE IN BLEACH, SO ALL HELL HAS BROKEN LOOSE IN THIS MANGA. At this point Kubo can do whatever he wants and go in whatever direction he wants and it'll all make "sense."
Don't worry guys, we have until "Deicide 18" until all this filler crap is over with.
