Was it maybe an action slip, with the student deliberately removing the guard and then pulling the mixture, thinking they were applying the correct sequence of actions to apply carb heat?
This is exactly what happened to me. The student had always been very mindful and deliberate in their actions, but for some reason went for the wrong control. You may be surprised at how smoothly and quickly your hand can move the guard and press the button to activate the control. We walked away without injury thankfully, but I changed a couple things about the way I taught those controls.
