Aizen never called out his sword's name. He's stated that when KS is released is when it places them under his hypnosis. During the "fight" with Aizen back in Soul Society, Aizen did 1 attack on Ichigo, and that was to nearly cut him in half. He never said "Shatter KS". Ichigo also saw through the switch with Hinomori after everyone else was attacking. Then there was Ichigo's comment about Aizen not even using his shikai when they fought in Soul Society when Unohana was restoring his spiritual pressure.
