Kane felt that he was too late to intervene. His intention was to interrupt the statue at a crucial point when it was about to attack. This would make the interference extremely effective and he would not make himself an obvious target for something that was as powerful as the statue. What he did not expect was the absolute ability to not have any activation time at all. The damage had already been done before he could do anything.
When he saw that his command worked, he quickly climbed on Cliffripper's back while carefully avoiding the spikes on the beast's back before they quickly relocated. If that thing discovered his location, he would be killed instantly.
