Pretty sure it was just being shown from Ichigo's point of view attacking Shaz. The white explosion wasn't necessarily Ichigo using Getsuga Tensho but just him attacking in general. I think it's happened more than once that Ichigo has just swung his sword and made an explosion. I doubt Shaz is dead seeing as how that would be a waste, just probably greatly injured or incapacitated. I think everyone is over thinking this.
